tests/test_lightningd.py: make test less flaky.

Browse source 
When we drop an HTLC_ADD packet, sometimes the commit timer fires
before we try to read from the fd.  In this case, the payment is
considered committed and we don't fail.

We need manual commit to work around this, and also we'd need to do
the pay command asynchronously from python because it will block.
That's a bit out of scope for now, so just handle either way.
