[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.
