Lint seed scripts

[maxceem]

So far we have excluded seed scripts which can be run by npm run demo-data from linter.
Linter should be enabled for them and issues have to be fixed, as we are going to constantly update and improve these scripts.

The rule for console.log should be disabled in seed scripts as we use it to output log.

Alternatively, we may use logger, but I don't see a strong benefit for it in these scripts.
