fix: avoid suspend call inside non-inline removeAll(predicate)

removeAll { assetDao.getAsset(...) } failed to compile ("Suspension
functions can only be called within coroutine body"). filter{} is
unambiguously inline and safe for a suspend call inside a suspend
function; pair it with the plain Collection-based removeAll(elements)
overload instead, which takes no lambda at all.
