This was the behaviour before, but got lost when ._reset_counts() was
added. Also added the check back to schedv2:fillRev(), which also
appears to have gotten lost in the move to ._reset_counts()
Just a stop-gap fix until this code can get a proper rewrite.
- wins back the performance lost by the decks and dconf not being
in memory, and the overhead of serializing data for DB calls
- card counts are no longer capped to 1000
- learn counts are currently still calculated separately - can't merge
v1 counts without changing the existing behaviour
- partially rendering the tree may yield more savings
- the old "mutate but don't save" approach to resetting the "done today"
counts no longer works, and was inefficient anyway - now we just check
the day when returning the count
- remove separate implementation for v1 scheduler
This is a stop-gap solution - a bigger refactor will need to wait
until the deck/note type changes have stabilized.
The progress bar add-ons appear to be the only active users of it;
they can switch their old code from iterating over the list to
simply locating the selected deck in deckDueTree(), as its counts should
summarize all the child decks.
- on collection load, the schema is upgraded to 12
- on collection close, the changes are reversed so older clients
can continue to open the collection
- in the future, we could potentially skip the reversal except
when exporting/doing a full sync
- the same approach should work for decks, note types and tags in the
future too
- the deck list code needs updating to cache the deck confs for the
life of the call
