cards must be removed from filtered decks before they're buried

if not, removeLrn() resets due=odue and odue=0, leading to an invalid
delay calculation when they're later reviewed in the filtered deck

to fix this we'll need to make the same changes required to support
learning cards retaining their state when being emptied from a
filtered deck
