Fix dépense annuelle regex - see HEA-846

This removes the regex for `(?:dépense annuelle|unité)` and
the tests for it - because there are no BSSs that have that as
a complete label. All the examples actually include the name
of a product and need a regex like:
`{product_pattern}{separator_pattern} (?:dépense annuelle|quantité annuelle)`
