Resolve "Members page breaks after removing a user and doesnt let you remove any more unless you refresh"

Basically, the issue was that when we force removed a user from the store, we had to pass a userId for the store to identify if the current user is being removed or not.

That id passed was always the id of the currently logged in user so we always kicked ourselves out from the store. It should have been the id of the user being removed instead which is what this MR changes.

Closes #1393 (closed)
