Subject: Check written bytes are not None before summing them to offset

Because purely written streams could return None instead of written
bytes, we cannot sum them to offset integer. On such case let
assume data has been written all at once.

This fixes LaunchPad [#1845631](https://bugs.launchpad.net/subunit/+bug/1845631)
