Update invite_group_spec to be consistent with EE
What does this MR do?
Resolves an issue where tests for the invite group/members feature had different specs between CE and EE.
This makes the spec file consistent with the one in EE.
Also updates some naming since I may have been overzealous with renaming "Share" with "Invite".
