res_xmpp: Correct implementation of JABBER_STATUS & JabberStatus

The documentation for JABBER_STATUS (and the deprecated JabberStatus
app) indicate that a return value of 7 indicates that the specified
buddy was not in the roster. It also indicates that you can specify a
"bare" JID (one without a resource). Unfortunately the actual behavior
does not match the documented behavior.

Assuming that our roster includes the buddy online and available
"valid at example.org/Valid" and does *not* include the buddy
"invalid at example.org", the JABBER_STATUS() function returns the
following before this patch:

+------------------------------+------------+--------------------------+
| Buddy                        | Status     | Result                   |
+------------------------------+------------+--------------------------+
| valid at example.org            |  Online    |  7 (Not in roster)       |
| valid at example.org/Valid      |  Online    |  1 (Online)              |
| valid at example.org/Invalid    |  N/A       |  7 (Not in roster)       |
| invalid at example.org          |  N/A       |  Error logged, no return |
| invalid at example.org/Valid    |  N/A       |  Error logged, no return |
+------------------------------+------------+--------------------------+

And after this patch:

+------------------------------+------------+--------------------------+
| Buddy                        | Status     | Result                   |
+------------------------------+------------+--------------------------+
| valid at example.org            |  Online    |  1 (Online)              |
| valid at example.org/Valid      |  Online    |  1 (Online)              |
| valid at example.org/Invalid    |  N/A       |  6 (Offline)             |
| invalid at example.org          |  N/A       |  7 (Not in roster)       |
| invalid at example.org/Valid    |  N/A       |  7 (Not in roster)       |
+------------------------------+------------+--------------------------+

This brings the behavior in line with the documentation.
