wrap all "uninstall filter" calls in try ... catch
when websocket connection is closed, "uninstall" method in _FilterEngine throws exception with message from RPC Server "-32000 subscription not found" that stops application and i dont know where we able to catch it.
I think ignoring the exceptions when unregistering a filter is reasonable. Do you want to open a PR for that?
ok, i'll open PR later
So, where should we catch exceptions after all?
