[bug] fix early append notification
There's a workaround for "slow" APPENDS to an inbox, and it is that we have a flag to allow returning early when JUST the mdoc (the meta-document) has been written. However, this was givin a problem when doing a FETCH right after an APPEND (with notify_just_mdoc=True) has been done. This commit fixes it by making the FETCH command first check if there's an ongoing pending write, and queueing itself right after the write queue has been completed. This fixes the testFullAppend regression. Releases: 0.4.0
