* Fix GetType() bad pattern and related issues in tests $var.GetType() can raise an exception in tests so we should check $var before make the call. A large part of the tests does not make this check. I start with searching ".GetType()" but discovered many related issues in tests (reduntant and unneeded tests, "throw" bad pattens, bugs, formattings (sorry!) and so on) - I had to fix them too. * Fix after code review * Second wave of migration GetType() -> BeOfType Removed 'GetType().Name' patterns.
