Another "not all code paths end in a return statement" case

[vudaltsov]

I have another issue that appeared in 3.17. I thought it will be covered by the fix for #4327, but the error is still thrown in 3.17.2.

I found these snippets:

<?php

final class A
{
    private ?string $property = null;

    public function handle(string $arg): string
    {
        if (null !== $this->property) {
            return $arg;
        }

        try {
            return $arg;
        } finally {
        }
    }
}

Psalm output (using commit 2902a8c):

ERROR: InvalidReturnType - 7:42 - Not all code paths of A::handle end in a return statement, return type string expected
