[Sync] Disable an integration test for the SharingMessage.

The test should check that the sharing message will be sent to the
server again if there was AUTH_ERROR in the last request. However the
SharingMessage data type doesn't always generate data for the next
commit requests.

This CL disables the test until it gets fixed because it might fail in
other CLs.
