Description of motivation.
We currently have two different behaviors for the code related to
"CodeException":
```
$codebase->config->throw_exception = true; // or false
```
If "throw_exception" is set to `true`, code execution stops.
If "throw_exception" is set to `false`, the code may continue
to execute, and an error may potentially occur.
This commit allows testing for the second case, when the value of
"throw_exception" will be "false".
Failed tests:
```
1) MagicMethodAnnotationTest::testInvalidCode with data set "staticInvocationWithInstanceMethodFoo"
Failed asserting that exception of type "Psalm\Exception\CodeException" is thrown.
2) MagicMethodAnnotationTest::testInvalidCode with data set "nonStaticSelfCallWithInstanceMethodFoo"
Failed asserting that exception of type "Psalm\Exception\CodeException" is thrown.
```
This test has been failed with an error "UndefinedMethod".
This error is being issued correctly.
But so that this error would not interfere with the test, it was suppressed.
Fixed problem:
```
MagicMethodAnnotationTest::testValidCode with data set "magicStaticMethodInheritanceWithoutCallStatic"
Psalm\Exception\CodeException: UndefinedMethod - src/somefile.php:9:32 - Method B::bar does not exist
```
Failed test:
```
1) MagicMethodAnnotationTest::testAnnotationWithoutCallConfigWithExtendsWithStatic
Failed asserting that exception of type "Psalm\Exception\CodeException" is thrown.
```
List failed tests:
```

3) Psalm\Tests\MagicMethodAnnotationTest::testInvalidCode with data set "inheritSealedMethodsWithStatic"

All we really need is for the source to be autoloadable, and it includes
all classlikes (interfaces, classes, enums and traits at the time of
writing).
