Lint rules prevent:
* Invalid naming conventions for new migrations
* Loop constructs in migrations - these should be used with caution
and are therefore a warning rule, use `// eslint-disable-next-line
no-restricted-syntax` to prevent this rule from firing where a loop is
required
* Returing within a loop - this is usually meant to be a
continue/break
* Multiple joins - these can be badly performing migrations, so should
be treated with caution, disable the rule for the line if the risk is
understood / the migration cannot be written without it

Since we had a bug where members with a canceled subscription would have
a status of 'comped' we must fix any existing members in this state.
We update all members which have no products to a status of 'free',
which is the definition of a 'free' member.
