wallet/db: don't use migration_context.
`struct lightningd` is not completely initialized, so we added a "migration_context" which only had some of the fields. But we ended up handing in `struct lightningd` anyway, so I don't think this complexity is worthwhile. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
