Search email and search phone test intents

Bring back support for ACTION_SEARCH_EMAIL and ACTION_SEARCH_PHONE
in the AllIntentsActivity test. It was removed in
Iad3c19262b22fb2345bbff42707e1a4d186c0a62.

Since the code has changed a lot, we no longer have a search activity to
allow search over just emails or just phone numbers. Hence, just
have the People app handle the intent and redirect to a search
with the provided query.

This works aside from this separate bug of the query not
showing up (bug 5790409).
