[testnet][hf17] 8 of 12 nodes stuck on block 489630 right after hardfork 17

[mbg033]

All seednodes + one new test node continue mining blocks.
When some of the "stucked" nodes performs handshake - node receiving handshake drops connection with the message:

COMMAND_HANDSHAKE came, but process_payload_sync_data returned false, dropping connection.

Code with condition

and values of the variables:

version: 16, get_ideal_hard_fork_version: 17, hsdh.top_version: 17, hshd.current_height: 489630

HF17 height is 489630

fixed with #357
