stash-vr-companion fails when tags already exist with different case

[devloch]

If your stash instance already has some of the export tags configured except with a different case, it will fail to start up, as
if t not in tags_cache.keys(): print("creating tag " +t) createTagWithName(t)

will attempt to create the tag, which will then fail, because Stash does not allow for tags that are identical except for case.

It's an easy fix on the stash side, just wanted to document that I ran into it for any help/complaints (particularly, it showed up because 'Fisheye' is a saved/managed tag in some scenes in stashdb). While it would be simple to fix the for loop that's going through tags, that would invisibly break later flows as scenes wouldn't pick up on having the tag.

But like I mentioned, very easy for a user to fix - just check tags (particularly 'Fisheye' to make sure none of them are present but with the wrong case.
