Fix bugs with Remote Connection Services.

1. A previous change was made in ConnectionServiceAdapterServant to add
another parameter, requiring the user of SomeArgs.  I think this fix is
pretty self-explanatory.  (facepalm)
2. queryRemoteConnectionServices in ConnectionServiceAdapter had an issue
where the callback would not get called if there was more than one
IConnectionServiceAdapter instances.  This isn't an error condition, but
a condition where we don't query telecom for the list of valid remote
connection services.  We ensure a callback with an empty list is made
(this is similar to what Telecom already does).
This seems to be an issue inherent with DSDS because there can be multiple
SIM ConnectionServices where before there was only one.

Test: Run CTS tests.
