Remove the work badge icon for Google caller id in call log

An extended directory is custom directory in the app,
but not a directory provided by framework. So it can't
be USER_TYPE_WORK

When a search result is selected, RegularSearchFragment
calls getContactInfo and caches the resulting @{link ContactInfo}
into a local db. Set userType to USER_TYPE_WORK only
if it's NOT extended directory id and is enterprise directory
