Ensure error messages display on FE when a Contact cannot be created/saved

[epintozzi]

We currently have a handful of actions on our BE that will send errors to the FE for Company. Please ensure these errors messages will display and that we are testing them as such for the FE:

• 404 on index
• 422 on create
• 404 on create
• 404 on show
• 404 on update
• 422 on update
• 404 on destroy
• 422 on destroy
