When we begin claiming a payment, we move the tracking of it from `claimable_payments` to `claiming_payments`. This ensures we only ever have one payment which is in the process of being claimed with a given payment hash at a time and lets us keep track of when all parts have been claimed with their `ChannelMonitor`s. However, on startup, we check that failing to move a payment from `claimable_payments` to `claiming_payments` we check that it is not present in `claiming_payments`. This is fine if the payment doesn't exist, but if the payment has already started being claimed, this will fail and we'll refuse to deserialize the `ChannelManager` (with a `debug_assert` failure in debug mode). Here we resolve this by checking if a payment is already being claimed before we attempt to initiate claiming and skip the failing check in that case.
