BUG/MEDIUM: peers: reset commitupdate value in new conns

Browse Source 
The commitupdate value of the table is used to check if the update
is still pending for a push for all peers. To be sure to not miss a
push we reset it just after a handshake success.

This patch should be backported on all supported branches ( >= 1.6 )
