Add Recent Query Suggestions

Modify `CardSearchProvider` to return a cursor with recent queries when a search is performed. I think this requires creating a new database table for recent queries and returning a cursor to that table's columns when there is no text to suggest with yet.

It also requires saving queries to that table whenever a search by name is performed from anywhere.
