5136: fix multiple invocations of /keys callback.

Basically, we allow such a callback to be invoked only once.
Subsequent invocations (due to keys updates / whatever) cause
the callback to simply return in a do-nothing fashion.

Also: adding a /wire CMD - that uses /keys - after serilized
keys have been loaded.
