Fix selecting the first index

Browse source 
The way a QCompleter works is that it grabs whatever
data it has in the completerRole and sets it back on
the line edit.

I Bypassed the QCompleter delegate to show something
other than the completerRole (so, for instance, if you
write 'B', you could get 'Blue Hole' as the returned text,
but in fact the QCompleter has the 'B' as internal string
(because of the weird - and wrong way in which we are
dealing with completion - trying to complete for something
that's not inside the model yet).

So I hooked up a signal that will listen to the complete's
index, and if it's the first row() it's surely the special
case - then we bypass QCompleter return string and use
our own.
