Fix filtering when using a smart group

[seamuslee001]

I was testing this extension with a client site what I found was that when I was using a smart group as the include group it is possible that results weren't able to found because it was joining to the wrong table.

civicrm_group_contact is used for static group and manually added contacts to groups. However when the smart group cache is populated those contacts are also added to the cache table. The cache table also doesn't have a status field as it is limited to just contacts that are in the group

Also I know of at least one site that has dropped the id auto increment column from the cache tables so this handles that situation as well.

Thanks @seamuslee001, I created a new beta release (https://github.com/systopia/de.systopia.xdedupe/releases/tag/1.2-beta2). If you give me a shout in a couple if days/weeks if it's working, I'll (finally) release a 1.2.0.
