Bug report

Phpstan fails to find class constants when used as default argument value in a trait method. I have backtracked various phpstan versions. This has not been an issue up until phpstan 0.12.25, from 0.12.26 onwards it breaks on all versions i checked including the latest 0.12.58.

Code snippet that reproduces the problem

Things I have tried to make it pass:

• constant visibility does not matter
• method visibility does not matter
• declaring class as final or not does not matter
• the class extending a parent class does not matter
• not declaring strict types does not matter
• accessing the same constant from inside the method's body instead of the argument default value works fine: https://phpstan.org/r/2dd6fcf6-b07d-4ea6-9958-97c7393d24f0

Expected output

No errors.
