[encointer] fix missing hook for enactment of proposals (#508)

The first 4 Encointer democracy proposals have been up for vote and two
proposals have been approved. However, we realized that enactment did
not happen. This is due to a missing hook in the runtime.

This PR should fix the hook and enact the already approved after the
next runtime upgrade when the cycle phase changes to "assigning"
