PartDesign/Feature: add an optional parameter to getBaseObject() to prevent it from throwing exceptions

Browse Source 
In most cases getBaseObject() is used with an exception handler which
only detects if it failed but not the reason. This modification allows
to use it without excess exception handlers.
Also add the same parameter to SketchBased::getVerifiedSketch().
