[FIX] web: monetary should reset on currency change

This reverts commit 839a07fbed4720fc71c070507c591295722df350.
Indeed, the system will need the `resetOnAnyFieldChange` option as the
`FieldMonetary` will need to be re-rendered if the currency changes.
This does not use the `_fetchSpecialData` system as it will be
refactored later and the currency can be fetched without RPC.
