undo: remove invalidate_dive_cache() call from make_first_dc()

Browse source 
The make_first_dc() function clones a dive with a certain dive
computer moved to the front. This is used by the
MoveDiveComputerToFront undo command.

make_first_dc() calls invalidate_dive(). However, the undo
command does that by itself on every undo/redo. Thus,
remove the call in make_first_dc().

Aside from consistency, the goal is to move invalidate_dive()
to command/* so that we can be more aggressive about the whole
topic: Store only "const dive *" pointers and thus force any
writing access to explicitly invalidate the dive cache.
