[RPC] AccInputHash Problems

[revitteth]

Initial solution (implemented):

Call the s/c, If it returns 0x00....set it to 0x00 (otherwise you are returning a accInputHash for the wrong batchNum)
if it returns a non-zero hash, just set it

Fix required:

Sync events SequenceBatches and from batch DB data you can compute all batches accInputHash and you store them in the DB.
When you save a batch in the DB during synchronization, also compute the accInputHash and store it.

Hey @revitteth is this done now.

This is connected to this issue: #898

We've implemented a solution where we calculate the accInputHash upon request on the RPC in this PR:
#1161

I am closing the current issue, since it is kind of repeating the connected one.
