Merge trips without modifying the GTK tree

This patch does 4 small divelist.c changes in the following
order of importance:

1) In find_trip_by_time() now there is a check if a trip is actually found
before looking at the "when" flag.

2) Make remember_tree_state() slighly safer. If for example we have recently
deleted a trip from the linked list, it may still exist in the GTK tree model,
thus we want to check when calling find_trip_by_time() if there is an actual
match before setting the "expanded" flag for a trip.

3) When merging two trips in merge_trips_cb(), only use the tree model
to retrieve the timestamps (DIVE_DATE) and then find matching trips with
find_matching_trip(). Once we have pointers to the two trips to be merged,
move dives from one to another iterating with add_dive_to_trip().

4) In merge_trips_cb() - remember the tree state, repopulate the tree and
restore tree state, since now we are not adding/removing rows directly.
