> Affects Versions: 0.22.0

> The top of FSEditLog.logSync has the following assertion:
> {code}
> assert editStreams.size() > 0 : "no editlog streams";
> {code}
> which should actually come after checking to see if the sync was already
> batched in by another thread.
> This is related to a second bug in which the same case causes synctxid to be
> reset to 0
