Private methods called with alternative casing are reported as not used

Bug report

PHPStan incorrectly reports a method is not used if it was (accidentally) called with a variant casing.
This could be misleading in the case that someone just accidentally made a typo when calling the method elsewhere.
If the method is reported as not used, I would assume it is safe to delete. Yet if it has been called, just with an alternate casing, this would result in the broken code if the method is removed. The strict rules correctly finds this case; however, they are not included or enabled by default.

Expected output

The method is not technically unused.
