Remove "eslint-disable" statements from on top of files

[yatki]

Expected behavior

We shouldn't disable eslint rules generally and especially in the whole file. If it's really necessary, It is possible to disable certain rules for certain code blocks. See: #disabling-rules-with-inline-comments

We should refactor the codebase and implement more convenient solutions.

Actual behavior

We are disabling eslint rules on top test files. See: test/unit/modules/accounts.js#L1

Steps to reproduce

Which version(s) does this affect? (Environment, OS, etc...)
