Wipe StateDB in cli command wipesql

Browse Source 
Also, in the cli commands `wipesql` and `discard`, always rebuild the current
checkpoint of the stateDBs to make sure it's in a consistent non-corrupted
state and do a reset afterwards.  These commands will allow reverting the
StateDB to a valid and consistent state in case a crash leaves the StateDB in a
corrupted state.
