Added Test cases for Defects those were related to Geometry.

<h4>Summary</h4>
There are many defects those are coming which are related to Geometry not working in specific scenarios. We have ASM Geometry Automation which deals with Unit Testing of each constructor, but we need to add more Test Cases  related to Geometry which includes Core Node dealing with Geometry nodes and many other scenario which we have not covered in ASM Geometry project. 

<h4>Changes</h4>
I have create another Class **GeometryDefectTests** in **WorkflowTests** Project. This will be a dedicated location for adding all Geometry related defects, which we cannot add to our main Geometry Automation. Right now I have added 5 tests those were generated from Defects.
