redirect to manage case screen after creating a case
Currently if you create a case from within a contact record, it redirects back to the contact's case tab, rather than directly into the manage case screen. I suspect in most uses cases the user would expect to be directed into the newly created case.
Note: redirection into the manage case screen was the behavior in v4.4. It was changed somewhere between that version and v4.6 (it's not clear if it was intentional).
