Bug report

Looks like PHPStan thinks there are four code paths may be executed:

• $fooCollection->add(Foo::class)
• $fooCollection->add(Bar::class)
• $barCollection->add(Foo::class)
• $barCollection->add(Bar::class)

But actually there are only two paths, $fooCollection->add(Foo::class) and $barCollection->add(Bar::class).

Expected output

No errors.
