When using auth.other() should still keep previous users data.

[websanova]

When a $auth.loginOther() is done the previous (admin) users data is wiped and replace with the "logged in as" users data. We should keep both copies as sometimes it's nice to still have the previous users (admin) info such as the name or id.

There are issues with a refresh as the stale data previous user data would need to be fetched in sync (maybe not such a great idea).

Other possibility is to put into local data (but also not so great). Might make this manual call user can make if they want to keep admin data locally.

killing this as it's too specialized, can be handled indiviudally by app.
