Our business has URLs like /node/sso/esi?&url=https%3A//redacted.banno.com/redacted/
This is obviously non-standard.
Running the URL through common.urlJoin messes it up unnecessarily.
This should be a safe change to avoid the "no-op" when outgoingPath is an empty string (making the call to common.urlJoin useless as far as I can tell)
