Show team drives results in file system search results.

SearchMetadata is used to query for recents and file system searches.

There are a number of folders under <drive> that are hidden by default,
and to be searched needed to be whitelisted. This adds team_drives to
the whitelist and adds unit tests to verify that team drives results
are returned in searches.
