Revert "if a new node enters the cluster, that node will already be frozen at start"

This is unnecessary due to 03e2e436db5cfd29a56d13f5d2101e42389bfc94.
Furthermore, if a node doesn't force an election but wins it then it
can fail to record that it is the new recovery master.  This can lead
to a reverse split brain where there is no recovery master.

This reverts commit c5035657606283d2e35bea40992505e84ca8e7be.
