Admin user list does not refresh after activating a user

[ml-evs]

It currently disappears; this is a bug introduced by me in a recent PR.

The problem seems to be in the UserTable.vue component (script -> methods -> updateUserStatus) at this line:

this.users = JSON.parse(JSON.stringify(getUsersList()));

I think this line isn't useful, as Vue already updates users when you change a user's Status. (And it failed because getUsersList() returns a promise and not just data)
