Remove pending admin team members

[KevinMulhern]

When I accidentally add someone to the admin team, I want to be able to remove that team member immediately, so someone doesn't gain access to admin when they shouldn't.

Acceptance criteria

1. Log into admin v2 - admin@odin.com, password123
2. Invite a new team member
3. Click the ellipsis menu on the new team member
4. Click the "Remove" option
5. The new pending team member should be deleted and removed from the team member list

Note:

• The remove option should only be available on pending team members.
