Alphabet nodes synchronize list of alphabet keys from main chain
`NeoFSAlphabet` role once per epoch. This can lead to a wrong behavior in
single chain deployment (`without_mainnet` config parameter). Alphabet node
in single chain environment will try to get NeoFSAlphabet role from main
chain client, but it'll get result from side chain instead. Side chain
stores list of all inner ring nodes in this role. Therefore it is possible
that alphabet nodes will try to appoint inner ring nodes as alphabet nodes,
which is not correct.

Extra blocks for notary deposit must not be less than extra blocks
at notary tx rounding.
Consider you make notary deposit every 1000 block for next
1100 blocks. At block 555 you made notary deposit up to 1655.
At block 1554 you want to send notary tx. Notary client uses rounding
to calculate `until` value. By default notary client rounds with up
to 150 block ahead, thus for tx at 1554 `until` will be 1700.
1700 is bigger than deposit limit at 1655 and tx will fail. However
if extra blocks for notary deposit will be 200, then this case
won't be possible.
