Issue Summary

When clicking on "Add existing calendar" option on Team Calendars screen, the list of existing calendars is shown ordered by Subscribers in an ascending manner. This results in UI showing the least popular calendars first - in order to see the more popular calendars it's necessary to scroll to the bottom of the list.

Steps to Reproduce

1. Add three users in Confluence (user1, user2, user3)
2. Create three calendars in Team Calendars (Calendar1, Calendar2, Calendar3)
3. Make user1 watch Calendar1
4. Make user2 watch Calendar1 and Calendar2
5. Make user3 watch all three calendars
6. Go to ellipsis and click on "Add existing calendar"

Expected Results

A list of existing calendars is shown ordered by "Subscribers" in a descending manner.

Actual Results

A list of existing calendars is shown ordered by "Subscribers" in an ascending manner.

Notes

The bug does not manifest itself on older TC versions like 6.0.25.

Workaround

Currently, there is no known workaround for this behavior other than using an older version of Team Calendars. A workaround will be added here when available.
