Fix closure to have storage bug in codeAction

[tm1000]

This PR fixes the following bug introduced into codeAction as a result of the underlying cache being empty when creating new files while using the language server

[Error - 11:05:08 PM] Request textDocument/codeAction failed.
  Message: UnexpectedValueException: Expecting /project/myTestFile.php:27:531:-:closure to have storage in /project/myTestFile.php in /project/vendor/vimeo/psalm/src/Psalm/Codebase.php:650

It's actually almost the same as #7247 except I didn't add the try/catch to my own code! 🤕

Additionally this adds a quick speedup to codeAction by adding a cache whenemitIssues is called so that we don't have to run the IssueBuffer everytime codeAction is called (which in vscode is a lot because every time the mouse or cursor moves a codeAction is sent). Instead we just ask the LanguageServer to give us the previous issues returned from IssueBuffer through the use of the method getCurrentIssues

Sorry for the other PR. I didn't realize you started work on v5 and set the default branch to 4.x

test-with-real-projects is failing on the following cause:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - azjezz/psl is present at version 1.9.x-dev and cannot be modified by Composer
    - php-standard-library/psalm-plugin 2.0.0 conflicts with azjezz/psl <2.0.
    - Root composer.json requires php-standard-library/psalm-plugin ^2.0 -> satisfiable by php-standard-library/psalm-plugin[2.0.0].

You can also try re-running composer require with an explicit version constraint, e.g. "composer require php-standard-library/psalm-plugin:*" to figure out if any version is installable, or "composer require php-standard-library/psalm-plugin:^2.1" if you know which you need.

Installation failed, reverting ./composer.json to its original content

So nothing to do with this commit.
