Load inbox only on first appearance; refresh via pull-to-refresh; bump to 2.2

.task fires on every appearance, including popping back from a PR detail, so
the landing page re-ran the full network refresh on each back navigation.
Guard the initial load with didInitialLoad so the list loads once and then
only refreshes when the user pulls down. Bump to 2.2.
