Album.sortTags argument ignored

[simoncn]

When a tag is missing, sorting by that tag sorts the missing tag to the end of the list. Because you have specified -incdate in indexTags, the order is reversed and the missing tags come first. I think it would be better to always sort missing tags to the end, whether or not the indexTags entry has a -.

It is not possible to provide a default value for missing tags and it is not possible to exclude missing tags from the sorted list.
