Trim Action for self-intersecting polygons during Project Creation fails with no error message

[ramyaragupathy]

Current Behaviour:

When a user creates a project area that's self intersecting, Trim Action results in Exception and error is logged in the backend.
Example error log:

TopologyException: Input geom 0 is invalid: Self-intersection at or near point -21.006146092804485 -20.134594635489307 at -21.006146092804485 -20.134594635489307 [2021-10-25 23:01:48,131] CRITICAL in actions: IntersectingTiles GET API - unhandled error: The operation 'GEOSIntersection_r' could not be performed. Likely cause is invalidity of the geometry <shapely.geometry.multipolygon.MultiPolygon object at 0x10736d5e0>

Expected Behaviour:

If the input polygon is self-intersecting, indicate the issue to the user when the Trim Action is initiated.
