Make the first filename on the command line the default filename

From a usecase point of view - if we call with multiple file names then
most likely it's

subsurface MyDives.xml new_dive1.xml new_dive2.xml

and therefore the existing "database" is the first filename, not the last
one (as the current implementation assumes).

Frankly, this is a bit arbitrary - but this one seems to make more sense.
