Fixes to LSP protocol (#4143) 
* Fix missing parameter in LSP textDocument.didChange

This parameter was accepted, but not documented. Since the JSON-RPC
Dispatcher looks at the comments for type information, it would fail
to find info and produce:

    PHP Notice: Undefined offset: 1 in vendor/felixfbecker/advanced-json-rpc/lib/Dispatcher.php on line 141

Combined with issue #4142, this ended up violating the protocol.

* Ignore out-of-project files in textDocument.completion

Other methods, such as didOpen and didChange already checked for this,
but completion did not. This would lead to funny behaviour, where
triggering completion would cause the file to be analyzed, but only
using the on-disk state. And any changes to the file would never be
analyzed.

This ignores out-of-project files for completion, too.

Add null as a possible type parameter to strval (#4100) 
https://www.php.net/manual/en/language.types.string.php#language.types.string.casting mentions

> `NULL` is always converted to an empty string.

Which seems to indicate that it is a valid argument for it.

As opposed to stringifying other types (like arrays), `strval(null)` does not cause a warning in PHP.

Test parallelization (#4045) 
* Run tests in random order

Being able to run tests in any order is a pre-requisite for being able
to run them in parallel.

* Reset type coverage between tests, fix affected tests

* Reset parser and lexer between test runs and on php version change

Previously lexer was reset, but parser kept the reference to the old
one, and reference to the parser was kept by StatementsProvider. This
resulted in order-dependent tests - if the parser was first initialized
with phpVersion set to 7.4 then arrow functions worked fine, but were
failing when the parser was initially constructed with settings for 7.3

This can be demonstrated on current master by upgrading to
nikic/php-parser:4.9 and running:

```
vendor/bin/phpunit --no-coverage --filter="inferredArgArrowFunction" tests/ClosureTest.php
```

Now all tests using PHP 7.4 features must set the PHP version
accordingly.

* Marked more tests using 7.4 syntax

* Reset newline-between-annotation flag between tests

* Resolve real paths before passing them to checkPaths

When checkPaths is called from psalm.php the paths are resolved, so we
just mimicking SUT behaviour here.

* Restore newline-between-annotations in DocCommentTest

* Tweak Appveyor caches

* Tweak TravisCI caches

* Tweak CircleCI caches

* Run tests in parallel

Use `vendor/bin/paratest` instead of `vendor/bin/phpunit`

* Use default paratest runner on Windows

WrapperRunner is not supported on Windows.

* TRAVIS_TAG could be empty

* Restore appveyor conditional caching

flag class_exists as impure per vimeo/psalm#3975 (#4004) 
`class_exists()` interacts with PHP's autoloader feature, which allows
user-defined behaviour to take place when PHP tries to load a given
class or interface.
