Refresh adapter on resuming, so that call dates are updated.

When not doing this, the call dates might be wrong (they might e.g. say

SmartDialer: show quick contact on long press

Instead of displaying the disambiguation dialog, show quick contact

well as perform other operations such as editing or messaging.

This is useful because it's easier to search for contacts via T9
compared to using the QWERTY keyboard.
