Desktop: enable clearing of dive site

Browse source 
Clearing dive site did not work for two reasons:
1) We didn't get a signal when editing was finished.
2) When clearing the dive site, the "add new dive site" site was set.

Thus, connect to the editingFinished signal and in
DiveLocationLineEdit::currDiveSite() return a null pointer if
the string is empty.

This means that it is not possible to have a dive site with an
empty string, but that shouldn't be a problem, right?

Fixes #2148
