Crash when returning undefined templated class with no docblock

Adding a docblock fixes it, even if the docblock doesn't specify the template: https://psalm.dev/r/31efc1de51

I found these snippets:

https://psalm.dev/r/3f50a48d4c

<?php

class Foo
{
    /** @var Bar<string> */
    private Bar $baz;
    
    public function __construct()
    {
        $this->baz = new Bar("baz");
    }
    
    public function getBar(): Bar
    {
        return $this->baz;
    }
}

Psalm encountered an internal error:

/vendor/vimeo/psalm/src/Psalm/Internal/Provider/ClassLikeStorageProvider.php: Could not get class storage for bar

https://psalm.dev/r/31efc1de51

<?php

class Foo
{
    /** @var Bar<string> */
    private Bar $baz;
    
    public function __construct()
    {
        $this->baz = new Bar("baz");
    }
    
    /** @return Bar */
    public function getBar(): Bar
    {
        return $this->baz;
    }
}

Psalm output (using commit afe85fa):

ERROR: UndefinedDocblockClass - 6:13 - Docblock-defined class, interface or enum named Bar does not exist

ERROR: UndefinedClass - 10:26 - Class, interface or enum named Bar does not exist

Seems fixed :)
