Currently when generating oneboxes if the connection timeouts and we’re
using the `FinalDestination#get` method, then it raises an exception.
We already catch this exception when using the
`FinalDestination#resolve` method so this patch just applies the same
logic to `FinalDestination#get`.
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
