private constructor with __callStatic fails with PropertyNotSetInConstructor

[pauljohnston2009]

using __callStatic with a private constructor errors with PropertyNotSetInConstructor

I figured out that it can be fixed it in a few ways don't use the magic __callStatic method (existing test that this works is already included https://github.com/vimeo/psalm/blob/0317f1dbece01849bbf9e51acd816cfe536e2a54/tests/PropertyTypeTest.php#L1719) eg. https://psalm.dev/r/aec125745e

or making the constructor public eg. https://psalm.dev/r/217a77d382

I expected the the magic method would not make a difference, and should be treated like any other static method.
