Normally I would let `eslint --fix` do this for me, but there's a bug
that causes:
const x = function ()
{
// ...
};
to become:
const x = ()
=> {
// ...
};
which ESLint thinks is a syntax error. (It probably is; I don't know
enough about the automatic semicolon insertion rules to be confident.)
The old loadSettings.js was a way of customizing settings upon load, because
the Settings module did not offer this functionality. But it did not work well,
since all the default settings were not loaded.
Let's get rid of loadSettings.js for the bulk of the tests (the "backend"
specs). For the "container" specs, we'll keep it in place until/if we rewrite
Settings.js making it less brittle.
