Fix currency replacements.

While loading an xml file, do not look up an internal commodity and modify that,
but rather work on a copy.  When inserting the commodity, apply the same
replacements as in gnc_commodity_table_lookup().

This change should not be necessary on branches/2.2 but it might not do any
harm.
