[FIX] account_statement_import_sheet_parser: prevent failing when ban…

…k-balance import

Problem: When the import expects to see the Amount field when
the amounts are split into Credit/Debit. Attempting to import
throws the error "Bad file/mapping: 'Amount' is not in list".
this fix sets the relevant fields to False depending on the
type of import selected by the user.
