profile: explicitly update profile items

Instead of listening to the dive-data-model changed and
axis changed signals, update the profile items explicitly
once per plot() call. This avoids double replotting of the
dive items.

The old code had at least two replots per plot() call:
one after profileYAxis()->setMaximum() and one after
dataModel->emitDataChanged().
