[DO NOT MERGE] Fix Dialer crash loop for caller id in personal contact directory

The bug is dialer queries CP2 for alternative name by lookup key of personal directory
CP2 throws IllegalArgumentException as the lookup key is not found locally

slient IllegalArgumentException since alternative name is not very important to crash dialer.
(It's a fix by reverting some changes in ag/880910)
