Update queryRemoteConnectionServices to fix failing CTS tests.

Yes, it seems counterintuitive to change code to fix failing CTS tests.
Recent changes, however, assumed that we'd only return the sim connection
services which are associated with a connection manager via carrier config.
Turns out this means that you can NEVER make remote connections via the
cts tests since the test sim accounts don't have valid sub ids and thus
have no valid sim connection manager set up.  Yes, we should fix that in
the future, but for now this change relaxes the assumption we are sending
back only the sim accounts associated with a connection manager and instead
assumes we'll send back all sim accounts.  Its not perfect, but its also
in line with how this used to work in previous releases.

Test: Run CTS tests.
