Study list of users is not rendered correctly.

• Shared experiments do not show up in list of other users with which experiment is shared
• After moving to studies page, in which the shared experiment does appear, and moving back to users page, the experiments list is empty for all users.

I currently have no idea why this is no longer working and will need to investigate.

This issue is caused, and blocked, by vuex-orm/vuex-orm#602. The library maintainers are working on a fix for this, so I will not try to hack workarounds for now, unless it takes too long for this issue to get fixed upstream. I at least partially fixed this in that the app no longer errors out when a shared study is selected in the studies list, but the error described in this issue remains.
