NOVACLI: If searching for null suspect, produce message

In novacli, if you use the novacli get command to request info
about a suspect that doesn't exist, a message is now printed
instead of the uninitialized suspect's variables in suspect details
string form.

UI_CORE: Fix for most novacli options exiting early

Changed the bufferevent callback function MessageManager::WriteDispatcher to
only get triggered when StopNovad is called, and nowhere else. So that
we can still quit after that is called and written, but act normally
elsewhere.

NOVACLI: fix for error message

Changed the way that the conditional for testing a null suspect is done.
In addition, changed the order of how the REQUEST_SUSPECT_REPLY 
case is handled. Seems to indicate that it works fine now.

The LOG line for invalid config vars was very annoying. Two instances of 
ERROR, no spaces where there should be spaces, etc. Fixed it.
