`class-string|string` type is not simplified to `string`

[mvorisek]

Bug report

Starting with the latest phpstan release the following fix is needed: https://github.com/atk4/ui/pull/1657/files

But I belive it is wrong as class-string|string type should be simplified to string as before.

Also, as shown in the code snippet below, it is still/correctly simplified when declared as phpdoc.

Code snippet that reproduces the problem

Expected output

 Line | Error
 -- | --
- 8 | Property Cl::$u (A\|null) does not accept default value of type array<int\|string, class-string\|string>.
+ 8 | Property Cl::$u (A\|null) does not accept default value of type array<int\|string, string>.
 20 | Parameter #1 $x of method Cl::mm() expects array<int\|string, string>, null given.

@mvorisek After the latest commit in dev-master, PHPStan now reports different result with your code snippet:
