planner: move same-time check to DivePlannerPointsModel

Browse source 
There must not be two dive planner points at the same time
stamp, as this violates the laws of physics (and internal
assumptions).

The corresponding test was done in the profile code at
two different places with floating point arithmetics.
This is a bad idea, because
1) code duplication
2) danger of rounding issues

Instead, do this in one central point in the planner model
and use integer arithmetics. Simply add a few seconds until
a unique timestamp is obtained.
