Start the configure intent with the right user

When opening the ConnectionService's CONFIGURE activity, make sure
to direct it to the correct user.

Additionally, register SIM/SIP PhoneAccounts as MULTI_USER so that
secondary users can use them.

Finally, differentiate between work profile PhoneAccounts so that
they can be correctly identified by the user.
