Set colorControlActivated=colorPrimary

This affects the color of all controls once activated. For example: checked
checkboxes, selected radio buttons and focused EditTexts.

The new activited control color doesn't look good inside the
ContactSelectionActivity's SearchView. Therefore, I setup a custom theme for
this view.
