Can you please remove this from this PR? See #2920 (review).

I would also suggest to refactor the openEntryActions and approveEntry actions to a mixin, which then both inbox-list.vue and choose-thing-type.vue can import. This reduces code duplication and avoids further issues where those two provide different options.
