Switch eslint-plugin-jest rules from warn to error (#54)
Switch eslint-plugin-jest rules from warn to error (#54)

Follow-up to https://github.com/stylelint/stylelint/pull/3689#issuecomment-424256507.

Changes violations of `jest/no-identical-title` and `jest/prefer-to-have-length` to be marked as errors instead of warnings. This is part of the recommended config for `jest/no-identical-title` so I removed the local override.
