Search with repository query parameter should handle wildcards for group checks

When performing a search, you can pass in a repository query parameter to limit your results to items in the desired repository.  You can use wildcards to match many repositories if desired.  This is all working fine and well.  With NEXUS-18909 we reintroduced the ability to enter a group repository name, and have the query apply to all members of that group.

However, the change will only extrapolate groups to members if you have the exact repository name, i.e. no wildcards.  Once wildcards are introduced we revert back to the old functionality of simply matching against the repository name with no extrapolation out to any member repositories.  It would seem to properly support wildcards, that we should scan the repository list for any groups that match the query term (with or without wildcards) then extrapolate all matches members out into the query.
