[scan] Fix issue where albums get split

Browse Source 
Regression from PR #1655. This reverts the metadata search to the method used
before the PR, so that search is done in the order set by the metadata maps.

This means the songalbumid is set by the tag with the highest precedence, not
just the first one found.

Closes #1696
