The bib transformer task should not update the holdings HRID start number in Inventory HRID Settings

[branchedelac]

When wrapping up, rules_mapper_bibs.py calls self.store_hrid_settings().

This method resets the start numbers in the HRID settings for both instances and holdings.

This is not unlikely to lead to HRID conflicts down the line.

You will not be able to create new holdings if the following is true

• You transformed and loaded bibs
• You transformed and loaded holdings
• You transformed bibs again
