Minz request avoid custom methods (#4020)

Take advantage of PHP7+ null-coalescing operator `??` to make code more standard, shorter, and faster instead of custom function with no extra functionality.

Allows code to be better tested and fix two PHPstan errors:

```
 ------ -----------------------------------------
  Line   app/Controllers/configureController.php
 ------ -----------------------------------------
  410    Cannot unset offset 'rid' on string.
 ------ -----------------------------------------

 ------ ------------------------------------
  Line   lib/Minz/FrontController.php
 ------ ------------------------------------
  70     Cannot unset offset 'c' on string.
  71     Cannot unset offset 'a' on string.
 ------ ------------------------------------
```
