Use new description generation

[znarf]

• Remove hardcoded descriptions and use the generator in Sequelize hooks
• Fix a few typos in generator
• Fix directly related tests (snapshots and looking at description string)
• Fix indirectly broken tests (somehow the returned order is changing for Transactions)

Do we want to migrate past data?

For now, I don't think so. Main reason is that the generator is software based and we would need to iterate 1 by 1 on all transactions in the table.
