For example with `stats/100s` stats query is emitted every 100 seconds,
but currently it will be first emitted only after waiting for 100
seconds after `xamari xlog` startup, or after reconnection to eNB if eNB
itself was restarted. And this way it will be hard to interpret obtained
numbers in relation to last 100s time interval.

-> Start emitting queries right after reconnection / xlog start, so that
we see the values as observed at the beginning, and can compare result
of further queries to them.
