PR Summary

UseCompletionCompleters.GetMatchingResults inNounArgumentCompleter so-Noun parameter forGet-Command has support for single/double quotes.

Also made the following improvements:

• When-Verb is used, only get nouns which are possible with the following verbs.
• useSortedSet<string> withStringComparer.IgnoreCase to ensure all nouns are unique and sorted and case insensitive. Also removed previous LINQOrder() call with this change.
• WrapGet-Command logic intoCompletionCompleters.GetCommandInfo method. This can probably be used elsewhere and potentially reduce duplication of command querying code in completers. Also addusing for creating powershell instance so its automatically disposed.

I also added some tab completion tests which seem to be missing for this completer.
