Subject: [PATCH] repmgrd: check local connection after promoting local node

In theory the local connection should not be affected by the node's
promotion. However we're handing over control to an external command
which is usually just "repmgr standby promote", but could potentially
be a user-defined script with unknowable side effects. So it's
better to be safe than sorry.
