#7158 Fix water depth calculation for WBS plot.

Browse Source 
The first intersection between the well path and the GeoMech model
is the correct water depth only when well path starts outside the model.

Top of the bounding box is used as an estimated water depth when
there is no intersection. WBS curves are now disabled for this case.
