Summary of a problem or a feature request

optional return in function call report an wrong error

Code snippet that reproduces the problem

https://phpstan.org/r/1f7d9120dfb1ba424c1c00e2de646e24

Expected output

as getBar() return an object|null, the if return true only if getBar return an object, thus, we can call getId() on it.

testing explicitly strict equality with null works fine as showned here
