There are mainly 2 changes:
1. When '-ExcludeProperty' is specified but '-Property' is not, use "*" as the default value for '-Property'.
2. Allow 'Select-Object -Property noexist-name' to return a PSObject with property noexist-name, unless noexist-name itself contains wildcards.
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
