Put an assertion inside db.c, and run every command we do (in testing) through
a `check` variant.
I inserted a deliberate bug (made addpsbtoutput call wallet_get_newindex()
before returning when running `check`, and indeed, backtrace as expected.

This avoids the mess where we override db_fatal for teqsts, and keeps it
generic.
Also allows us to get rid of one #if DEVELOPER, and an ugly global for
bookkeeper.

and it was because we were ignoring errors.
