Summary:
This commit adds a new action, `removeThreadsFromView` to be proxied and
measured through the ThreadListActionsStore
This action can encompass many different actions, e.g.:
- unstarring in starred view
- changing unread in unread view
- Moving to inbox from trash
- archiving a search result (which won't actually remove it from the thread-list)
However, for now, we are only interested in timing actions that remove threads
from the inbox
Depends on D3983
