Notifications: skip resolve during boot (#330)

## Issue
- Large resolve count (albeit batched) on bootup.

## Changes
- Skip the call on bootup. The same call will happen when you click the notification bell, so it's not too late to resolve at that time.
- Added `true` to `doResolveUris` to return cached results, otherwise it will keep resolving the same channels every time we enter Notifications Page.
