* Test fixes and changes needed to support Pester 4.0.8
* Replace 'Should Contain' with new 'Should FileContentMatch' assertion
Explicitly check for string creation with write-output
* Use the current version of pester and install it in modulesDir
* Simplify logic for relative path test.
Multiple '..' is not needed for a relative path, a single one will do. Also, on multi-drive systems using split-path -noqualifier will probably do the wrong thing with regard to constructing a correct path.
Remove extraneous Should Not Throw test, if this throws, the test will fail, we don't need to explicitly assert the not throw
* In some environments it is possible that computer name is 'localhost', so that should be allowed
* [feature] Add link for migrating tests from Pester v3 to v4
Fix up capitalization and white space issues
Change one test to check FullyQualifiedErrorId rather than just `Should Throw`
* [feature] update invoke-item test to handle the case where multiple notepad processes are running
* Fix spelling issue with Pester 4x, calling it Pester 4 should be sufficient
