Switched position of buttons in profile/groups

**What does this MR do?**
This MR changes the position of the "Settings" button in the groups list of a user's profile. Very often you have the position of the "Leave" and the "Settings" switched throughout the list. The change makes the style of the page a bit more streamlined.
