settings_users: Fix sending queries to /json/bots endpoint.

Apparently, since 1948cb6a8949fe44b433193b09f3ea35236eaca5, we've been
sending requests by an administrator to change a user's name to the
/json/bots endpoint, which would end up changing the "bot owner" of
these objects to some random user.

We fix this by re-splitting the views code.
