eslint-config-sora

Removed newline-before-return & array-callback-return.

newline-before-return was causing a bunch of unecessary spaces where
there would be an if statement, set statement, and return statement.
While I think there needs to be spacing around it, it was causing a lot
of unecessary lines.

array-callback-return is problematic as nodejs is async, and there were
starting to be areas where a simple callback was expecting a return
statement, which doesn't make sense.
