it should be able to deal with this and retry until everything is ok

looks like it cannot parse an empty genesis_time in
https://github.com/Alethio/eth2stats-client/blob/master/beacon/teku/teku.go#L41
which is reported as long as teku hasn't found the genesis time yet.

v0.0.10 should pass over this a little bit better
