Allow deleting a call log entry in the call log UI and the call details UI.

In the call log UI, an entry can be deleted by selecting "delete" in its context menu.
In the call details UI, a "delete" button is added at the bottom.

The "delete" icon at the top right of the call details UI is removed.
