Duplicated track entries for albums

[languitar]

I am experiencing many duplicated track entries inside albums returned by mopidy-spotify. Especially when browsing the media library using ncmpcpp I see many of these and they make it hard to just add one album without having to manually delete the duplicated tracks again afterwards.

Examples:

This got worse after switching to the Web API for search, since the albums no longer has dates. Previously, the albums with the same name would at least be split if they were from different years. However, the problem still appeared for some albums even with dates.

This is sort of related to #11, since browse is currently implemented by searching iirc, so solving that would probably fix this.

Another option is to use the browse/lookup features of the API, as I mention in that issue (in jodals comment quoting me).
