make getViaTmpFrom no longer update location log
All callers adjusted to update it themselves.

In Command.ReKey, and Command.SetKey, the cleanup action already did,
so it was updating the log twice before.

This fixes a bug when annex.stalldetection is set, as now
Command.Transferrer can skip updating the location log, and let it be
updated by the calling process.
