profile: remove clearHandlers function (fixes crash)

Browse source 
Recently (674c20227b), the call to ProfileWidget::clearHandlers()
was moved from PlannerWidgets::replanDive() to ProfileWidget2.
This cause a crash, because the code assumes that the number
of elements in the handles-vector the divepointplanner model
is the same.

Clearing the handles violates this assumption. It turns out
that the clearHandlers() function is broken anyway: it clear
the handles-vector, but not the gases-vector, which should
likewise have the same number of elements. It appears that
the clearHandlers() function is an artifact and it is
mysterious how this has worked so far. Remove.
