/**
* Rebuild a URI with some ugly-ass handling of encoding.
*
* Basically the ID part of a Mopidy URI needs to be encoded, but the rest of the URI can't be.
* This means we need to break down the URI (decoded) and then reconstruct with an encoded ID.
* This is all required because he URI is passed to us *from* a URL which has been encoded for
* obvious reasons.
* We can't just run encodeURIComponent because it will encode ':' and '/' elements which are
* required to properly map to Mopidy's internal structure. Some things need encoding, and others
* need decoding *sigh*.
*
* Instead, we pluck the individual encodings as needed.
*
* For example somebackend:track:https://youtube.com/1234 would cause issues with the
* https:// section. Our explode-by-':' approach would break this type of URI.
