Wipe StateDB in cli command wipesql

Also added tracerr.Wrap(...) to missing places.

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.

Don't select extra columns in SQL, fix metrics query

In the metrics query, the estimatedTimeToForgeL1 was probably not being read
from the SQL query because it contained upper case letters, and in PostgreSQL
when identifiers are not double quoted they are case insensitive:

When resending an eth tx, always increase gas price

Fix unforged L1UserTxs query in forgeBatch

Previously the code was only querying the unforged L1UserTxs of a particular
queue, but this was incorrect because there are always two non-forged queues:
the frozen one and the open one.

Replace it by a query to all the unforged L1UserTxs via a new HistoryDB method.

Incrementing the gas price unconditionally avoids sending the exact same
transaction, which geth will reject because that transaction already exists in
the pool
