Set maximum allowed push id to large value in QuicSpdyClientSessionTest.TooManyPushPromises.

This test fails in Chromium with "excessive output", blocking QUICHE merge.
Without a large maximum allowed push id, a large number of gMock warnings are
printed about uninteresting CloseConnection() calls.  The test passes because
MockQuicSpdySession::CloseConnection() is mocked out, but Chromium does not
stomach the output volume.

gfe-relnote: n/a, test-only change.
