fix misbehaving simulnet fastsync test (#1227)

Browse source 
* fix misbehaving simulnet fastsync test
cleanup redundant cutoff vs bitmap params is rewind and check_compact

* make sure we do not verify full kernel history on a writeable txhashset extension
rework simulnet simulate_fast_sync test to be more robust

* fixup store tests

* sleep for a bit longer to give nodes time to update
their sync_state correctly

* tweak timing of simulate_block_propagation
