**issue:** 

while doing stage_exec from scratch, `SeekCommitment` restores state
with (block=0, txNum=1). This skips over the txNum=0 tx, whose
processing populates the ibs with genesis information in
`TxTask#Execute`. Downstream, this leads to state root mismatch.

**context:** 

i was doing stage_exec from genesis in gnosis.

**fix** 
- when SyncStageProgress is x, it typically means that block x is
executed completely. Except when blockNum = 0, then it could either mean
that block executed completely (so restored txnum = 1) or not (restored
txnum=0)
- for block=0, we should consider the latter (txnum=0), because if we're
doing execution from scratch, it'll typically be with txnum=0. Half
block execution of genesis block (i.e. txnum=0 state is
processed/persisted, but txnum=1 not) is a hard to reach state.
