[#516] node: Send bootstrap request if attributes were updated

Browse source 
Consider following situation:
1. Epoch tick.
2. Update node attributes in the config.
3. Restart node.

Because we already sent bootstrap query after (1) and we are still
online, new bootstrap query won't be sent. This leads to the node
attributes being updated after another epoch.
