I believe lightning requests created before https://github.com/spesmilo/electrum/pull/7730
can have an amount of None - ones created after have amount 0 instead.
We could do a wallet db upgrade potentially.
Regardless, the type hint is `get_amount_sat(self) -> Union[int, str, None]`,
so None should be handled. (well, arguably "!" should be handled too...)

The 'height' field was added in cdfaaa2609
At the time we thought we could just add it with a default value without a db upgrade;
however the issue is that if old code tries to open a new db, it will fail (due to unexpected new field).
Hence it is better to do an explicit conversion where old code *knows* it cannot open the new db.
