* Fix going to definition on return type
If a return type of a method or function is set incorrectly (with the PHP doc), then the references are not added for the `function() : MyClass` symbol, so the "Go to definition" feature of the LSP won't work. I don't believe an invalid return type or not should stop the symbol location being tracked (and not allowing code navigation).
In moved the symbol location tracking to be before the return early short circuit.
* Update SymbolLookupTest.php

Currently it's not possible to "Go to definition" (LSP) on nullable args like `function( ?MyClass )` as the reference is stored a `MyClass|null` in the reference map, which will now resolve to a class name.
This PR removed any nullable type from the union before adding it to the reference map (as the reference map is only use to indicate a symbol was used in a given location, I think this makes sense).
This change avoids calling `str_replace()` on the original docblock and
instead only operates on the parsed (and modified) lines. This now makes
it so that if there are substrings of the docblock that match a tag
match, it won't get prematurely removed, therefore avoiding mangling of
the parsed docblock's description.
