Fix project creation (#1445)

* Add ability to change project name

* Fixed several issues where path types were changed

* Added PythonBindings CreateProject unit test

* Fix python warning format

* Validate new project name in CLI

* Fix issue creating pathview on linux

* Use better testing macros

* Refactored the unit_test_engine_template.py test to actually test
against the current engine_template.py commands

The commands of create-template, create-from-template, create-project
and create-gem is now being validated.

Registered the unit_test_engine_template.py script with CTest in the smoke test
suite so that it runs in Automated Review

Fixed issues in the engine_template.py script where the template_restricted_path parameter was required in the create_project and create_gem functions
