Fixes #4391. Weird situation where ForceDriver with args doesn't persists on open scenario (#4395)

Browse Source 
* Fixes #4391. Weird situation where ForceDriver with args doesn't persists on open scenario

* Prevents change ForceDriver if app it's already initialized and allowing also initialize with driver instead of only by driver name.

* Add dispose into FakeDriverBase and reset ForceDriver

* Moving test to Application folder

* Fix unit test

* Remove unnecessary GlobalTestSetup

* Add GC.SuppressFinalize

* Revert "Add GC.SuppressFinalize"

This reverts commit 2bd7cd7791.

* Reset MouseGrabView

* Avoid CI warnings

* Add GlobalTestSetup in all test that use Application

* Trying to fix unit test

* Reverting scope changes

* Remove UICatalog testing Run

* Force re-run CI test

* Fix merge errors

* Fix ansi for the red background color code

* Fix more ANSI color code unit tests
