eslint-ordering configuration updated

[xdrdak]

Description

we should be using ["builtin", "external", "internal", "parent", "sibling", "index"] instead of the airbnb defaults as the current setup is a bit too loose in how to order imports.

We will need to:

• add 'import/order': ['error', { groups: ['builtin', 'external', 'internal', 'parent', 'sibling', 'index'] }] to the .eslintrc.js rules object
• fix any potential errors that will arise (just run yarn lint --fix)

I would also add in internal before parent for path aliased imports. From the eslint-plugin-import docs:

3. "internal" modules
   // (if you have configured your path or webpack to handle your internal paths differently)

Updated issue description accordingly.

I was also thinking about using newlines-between option set as always for readability, what do you think?
