sqldb: rename 000009_payments to 000010_payments

The 000009 schema version slot is now taken by 000009_graph_v2_columns
which was merged ahead of the payments schema. Bump the payments schema
file number to 000010 to avoid the collision.

Moreover update the migration_dev.go file to reflect this change and
update the order of migration.
