Review recommended rules config for func-names and no-unused-expressions

[touzoku]

Currently 'func-names': ['error', 'always'] and 'no-unused-expressions': 'error' produce errors for a perfectly valid aura controller code as below:

({
    myAction: function (component, event, helper) {
        return false
    }
})

This issue requires research on how these rules could be improved (in lieu of just disabling them).
