Geary.App.FillWindowOperation: detect stale FillWindowOperations

Browse source 
When a user types in the search box, there may still be oustanding
FillWindowOperations queued on previous instances of SearchFolder
from previous keystrokes. This can result in a FillWindowOperation
with a stale value of ConversationMonitor.window_lowest from a previous
search executing on the current one. Detect this and return immediately.

Fixes: #838
