Before this change on first connect between primary and secondary we
initialize all the data. This is huge waste of time and resources if
there were no writes yet, as there is no real data to synchronize.

Optimize this by sending "virgin" argument to secondary, which gives it a hint
that synchronization is not needed.

In the common case (where noth nodes are configured at the same time) instead
of synchronizing everything, we don't synchronize at all.
