If REMOVEAGENTFROMGROUP core groups call fails because requesting agent does not have sufficient permission, return null failure result rather than true.

On non-HG this is on the only recognized failure state so we can return more information in the error result.
On HG there are multiple failure states which would require more work to distinguish, so currently return the unsatisfying "Internal Error" like some other existing calls.
