BUG/MEDIUM: peers: Don't start resync on reload if local peer is not up-to-date

Browse Source 
On a reload, if the previous resync was not finished, the freshly old worker
must not try to start a new resync. Otherwise, it will compete with the
older wokers, slowing down or blocking the resync. Only an up-to-date woker
must try to perform a local resync.

This patch must be backported as far as 2.0 (and maybe to 1.8 too).
