Ignored error on removed file doesn't trigger error unless cache is emptied #3058
Description
Bug report
If an error was ignored with a baseline, and then the file containing the error, phpstan doesn't notice that the error is not matched anymore because it doesn't analyze deleted files (obviously).
When cache is deleted, the error about unmatched error is shown.
Code snippet that reproduces the problem
$ echo '<?php print "abc";' > ok.php
$ echo '<?php print "abc" + 1;' > notok.php
$ /path/to/phpstan/bin/phpstan analyze --error-format=baselineNeon --level 8 . | tee phpstan-baseline.neon
