Renamed project from ASMGeometryTests to WorkflowTests.

Addressed all comments mentioned in pull request 1759 (https://github.com/DynamoDS/Dynamo/pull/1759)
Renamed folders, project and other necessary files.

@lukechurch : I hope I addressed all comments mentioned by you in our weekly meeting.
@pboyer : My main intention to add this project is to track our workflow on every build and if there is any regression we should get to know. I know it is difficult to track what makes it fail when graph is too complex but that we can resolve by running graph manually and see which nodes has errors.
