Placing job blocks prioritize transforming default villagers over relinking with existing professions

If you break a job site block bonded with a traded villager, replacing job block wont bond with same villager.

This allows for theoretically infinite worker villagers for only 1 job site block

Expected result: Replacing a job site block should 'bond' with an existing villager with the corresponding profession instead of transforming a default villager.

Picture is not super clear, but 2 of the villagers shown are traded and a third is also traded off screen. The 3 lecterns were broken and replaced in the same spot, now there are 6 librarians despite there only being 3 lecterns in the village
