Adds a number of safeguards against hanging transactions if the first statement of a transaction for whatever reason fails to return a transaction ID, or otherwise returns an unexpected error. This PR contains the following safeguards:

that is not aSpannerException

error. This will cause the transaction to be retried automatically.Fixes #799
