* Fix failing unit tests
Change team and user lists to specific classes derived from Collection<T> so we can offer better configuration of BranchProtectionPushRestriction via multiple ctors (teams only, users only, teams and users, etc)
Add another ctor to BranchProtectionPushRestrictions for the case where no teams/users are specified (ie admin only)
Change organization update tests to use this new ctor and assert we get empty lists rather than no push restrictions
- fix Update method PUT parameters
- add [SerializeNull] to various request fields
- fix deserialize problem with ProtectedBranchRestrictions ctor not being public
- tidy up DebuggerDisplay output
