Uemis downloader: fix algorithm to find matching dive details

Browse source 
Implemented suggestion from Dirk on how to deal with dive details
not being found.

Also cleaned up some unused variables, got rid of the last_log_file_nr
because it's not needed anymore.

One thing in question I still need to check is whether we really need to
decrease the dive_to_read if we find deleted dive details, this is still
in but I dont think it's really needed.
