[Merge] lp:~renatofilho/address-book-app/refactory-url-handler into lp:~phablet-team/address-book-app/staging

[Tiago Salem Herrmann]

Review: Needs Fixing

- the "+ new contact" button disappears once you perform a search.
- If I cancel the search it goes back to the regular contact list, but with the back button in the header. If I tap back the address-book-app is closed.
- the back/save button does not bring messaging-app back, just closes address-book-app and go back to the shell (we need to check what's the desired behavior here). If we wish to go back to the previous app, we may need to pass that into the url. Something like this:

addressbook:///addnewphone?phone=1234567&callback=messaging-app
