Subject: [PATCH] rpc: Move ValueFromAmount to core_write

This is necessary because core_write has to write amounts in
TxToUniv, and mistakingly uses FormatMoney for that
(which is only for debugging).

We don't move AmountFromValue at the same time, as
this is more challenging due to the RPCError depencency
there.
