refreshManually does not insert docs in view if they don't exist yet

[macrozone]

because of this issue #4

i need to manually refresh docs if the source collection has changed. However if the doc does not exist in the target view collection, it does not get inserted, because it asumes that the doc is already there.

Solution would be to do an upsert there instead of an update.
