fix: Correct default_order for not case-sensitive StringBones

[sveneberth]

Without the .idx suffix an empty result is returned

Hm, indeed this is a possible fix, but on the other side the order setting should be generally handled by the bones, and not in the prototypes, like in BaseBone.buildDBSort.

There's already pull request #1077 on this, which can be useful. Maybe it would be better to allow for a dict here as well, which is being fed to Query.mergeExternalFilter(), which then handles the ordering correctly?

Yeah, absolutely. After I found this bug I thought the same thing. But after looking at buildDBSort, I saw this only works on queries, we don't have here. Therefore, it was too much work for a hotfix. I'd appreciate to use the help of the bones, but for now let's go with this fix to get things working.

I've made an alternative proposal for this PR in #1169. It's not perfect, but uses the provided facilities.

Furthermore, #1077 was updated and tested now, and I would like to merge it into develop.
