* 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.
This restructuring moves tests to a directory name which matches the module
in which the cmdlet resides which should improve the discoverability of a
specific test.
For tests which are not about cmdlets in a module, new directories have been
created to make those tests easier to find as well
