[kronolith] Tags lost after Horde update

[Christopher 'm4z' Holm]

Greetings and thanks for doing Horde,

I recently updated our company Horde instance from version 5.0.2 (on
an ancient openSUSE 13.1) to 5.2.12 (openSUSE Leap 42.2). The upgrade
went well overall, but apparently, for all Kronolith events, the tags
are now missing from the "Tags" tab, these are all empty.
Looking at the "rampage_tag*" tables in the database, they still seem
to exist, however they aren't displayed at all. (Adding new tags seems
to work fine.)

How can I get the tags back? Or is this expected behaviour that I
overlooked in the change notes?
