[web] Introduce a migration that adds an actualizedCalendarQuery

Summary:
It is possible that the persisted keyserver infos don't have this field, and we need to add it.

Test Plan:

1. Modify a keyserver store transform so that we don't persist the query.
2. Run the web app and check if the rehydrated state doesn't contain the query.
3. Close the app, bump the code version and open the app. After the rehydration the query should be present.

Also checked if the migration doesn't break anything when the query was persisted.
