Get rid of some duplicated code and correct a connected line error.

When receiving a 200 OK response to an INVITE, it was possible to transmit two
connected line updates instead of a single one. Furthermore, the second did not
have the proper information present.

Now the two have been combined into a single update and the correct information
is presented.
