planner: fix gas selection

Browse source 
The lambda that created the list of gases took a copy not a
reference of the planned dive. Of course, that never had its
gases updated. Ultimately this would crash, because this sent
an index of "-1" on change.

Fix by
1) Using a reference to the dive, not the copy
2) Catch an invalid "-1" index (by Michael Keller <github@ike.ch>)

Fixes #4188
