FIX: /create_geometry routes GET and POST

[jvela018]

Fix to issue #194

Fixed the route to add both methods. Note that in the future it'd be ideal that functions are split into the most simplistic expressions. This way creating webapps becomes a lot easier/straight forward. It's good practice to use tools like Postman for these tasks. In this case it's quite a simple case but it gets hairy very fast otherwise.

With this fix you'll get:

• When connecting to the backend
  

• When creating a geometry
  

I didn't change the logger's message because I don't think we need an extra layer of complexity there.

@SMoraisAnsys,

Would you know why the Build and Smoke tests are failing? Any pointers are appreciated.
