[#480] ir: Do not sync alphabet keys in sidechain-only configuration

Browse source 
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.

Fix incorrect behavior with disabling of synchronization of alphabet keys in
sidechain-only mode.
