PSR12.Traits.UseDeclaration: check spacing after use keyword for mu…

…lti-line statements

While the `processUseStatement()` method checking single-line trait `use` statements would check the spacing after the `use` keyword, the `processUseGroup()` method checking multi-line trait `use` statements did not execute that same check, while the rule applies to both single- as well as multi-line `use` statements.

By moving the check for the spacing after the `use` keyword to the `process()` method, it will now be executed for both situations.

Tested by adjusting a pre-existing test.
