jack9603301 67df930184 [Part] Fix null pointer error in sweep operation 
When the spine line of the sweep operation of the part workbench depends
on the Sketcher document, if the dependent spine line drawn by this document
is deleted afterwards, the path variable will get a null pointer.
Due to programming errors, the standard judgment of this pointer is ignored, resulting in a crash.
Call IsNull() of the OCC document to determine the legitimacy of the shape.
If it is empty, an error is reported.

Fixes #0004764
