Incompletely migrated designations

In https://github.com/geolexica/isotc211-glossary/commit/26a947ca80fdf6883e1f9bec3d1db1909dccf79c, this databases now has list terms instead of one term, but they are missing synonyms.

Software implements logic for migrating legacy designations on-the-fly. Here is how it is done:

• Look if terms already exists. If it exists, do nothing.
• Create first designation of type “expression” based on legacy term
• Fill in first designation’s normativeStatus from classification
• Create additional designations based on legacy synonyms

The problem now is that there is terms that does not seem to include legacy synonyms. Software sees terms and does nothing, but terms does not include legacy synonyms, so synonyms never get migrated.

I am going to change the migration logic to look at “synonyms”, and if “synonyms” is present then perform a smaller migration to only deal with synonyms
