Revert "Add Call statistics to Contacts (Phone)"

This reverts commit d913804f8ac720b50d1d087a76e2edb384af942f.
Add Call statistics to Contacts (Phone)

Available from the local menu in the Phone application (except from
the Dialer Fragment).

Call-type filter can be selected in the actionbar.
If all call types are selected the incoming/outgoing rates show up in
blue/green respectively.
Tapping on an item starts a new activity that shows all call types with
details for the given contact or number.
