Duplicate No tag handler after upgrading to XenForo 2

Affected version

2.0.1

Someone was using an add-on of ours before upgrading to XenForo 2, and now they're getting the following error:

InvalidArgumentException: No tag handler for 'articles' src/XF/Repository/Tag.php:787

Currently looking into the exact cause, so this bug report may be a bit premature. Will update this thread when I find out more

Have done a bit of local testing, and it seems that I'm able to replicate it by having an add-on with custom tag handlers installed and then upgrading to XenForo 2. You can also replicate this error by inserting a row into xf_tag_content with a content type that doesn't have a tag handler

Ah, didn't see that. Thanks Chris! Will likely have this person remove the old records from xf_tag_content, I assume that should fix the issue as they're stuck with a pending tag recache currently
