Workaround NetworkConnectionManager race condition

Workaround NetworkConnectionManager race condition

Sometimes when GCM NetworkManager fires, Chromium doesn't yet know that
we have a connection, and reports the current connection type as
CONNECTION_NONE, even though android reports that we have a connection.
If we find a time when NetworkConnectionManager says there is no connection,
but android says there is a connection, send a valid connection type down
to the request coordinator, so it can start downloading a file.
We need to merge this to M56.
