Previously lnworker called LNWatcher.add_channel() on these, and then LNWatcher itself decided to unwatch them.

note: motivation related to https://github.com/spesmilo/electrum/pull/7932#discussion_r945755584 ,
where I have legacy (pre-staticremotekey) redeemed channels in a wallet.

So that the two methods are consistent with each other.
As concrete motivation, see e.g.
- how the `getrequest(key)` command calls `wallet.get_request(key)`, and
- the `delete_request(address)` command calls `wallet.delete_request(address)`
The _receive_requests dict is keyed by either 'address' or 'rhash' (see get_key_for_receive_request):
- 'rhash' is used if `req.lightning_invoice is not None`
- address is used otherwise
The `get_request_by_address` method was quite error-prone: it only worked for requests that had an LN part...
