invoices: always validate that LNInvoice.invoice can be decoded 
related: #6559

The LNInvoice.from_json() method previously did not validate, which is
used by e.g. wallet.import_invoices.

channel open: allow REMOTE to set htlc_minimum_msat to 0 
non-positive values do not make sense... but some nodes set it to 0
and if we enforce >= 1 then we can't open channels with those...
lnchannel._assert_can_add_htlc enforces positive values for HTLCs in any case.

lnchannel: better checks for "update_add_htlc" 
I believe this now implements all the checks listed in BOLT-02 for
update_add_htlc, however, the BOLT is sometimes ambiguous,
and actually the checks listed there IMO are insufficient.
There are still some TODOs, in part because of the above.

lnchannel: partly fix available_to_spend 
we were looking at inconsistent ctns
and we were looking at the wrong subject's ctx

all the FIXMEs and TODOs here will still warrant some attention.

(note that test_DesyncHTLCs was passing incorrectly:
the "assertRaises" was catching a different exception)
