Merged items still appear as duplicates

The remux items appear as their own individual item, in addition to being listed as a second version of the primary item.

I think MergeVersionsPostScanTask needs to update LinkedAlternateVersions in the primary, on top of setting the primary version ID for the linked items.

Something about this fix seems busted when the items have been previously imported and merged by an earlier version of the plugin. Setting LinkedAlternateVersions has no effect when performed on an instance of 10.10.6 that had its remuxes merged by version 2.0.1 of the plugin, but does work on both my 10.10.6 and 10.10.7 instances with freshly-created libraries and version 2.0.2.

Further, deleting the remuxed items and re-scanning doesn't clear out LinkedAlternateVersions on any version (which is a bug), so the merge task has no effect when it's run subsequently.

So I guess, don't use version 2.0.1?
