GeoProcessing - enhance user feedback when certain errors occurs

[MV88]

Description

We have to improve user notification. In cases where the process raise an exception we should also report it in the popup message. For example when the user tries to intersect a polygon (Intersection layer) with a point (Source layer) the WPS process returns the following exception where a message important for the user that is now not handled (also for this a new issue should be opened on the MS side @MV88 to be implemented now if the effort is small) assigned to @MV88:

<ows:ExceptionText>
  Process failed during execution
  java.lang.IllegalArgumentException: First feature collection must be polygonal or linear
  First feature collection must be polygonal or linear
</ows:ExceptionText>

Corresponding request to this output is here
