horde-db-migrate and horde-db-migrate-component need to use the same tab...

when horde-db-migrate-component is used using an app name like Horde_Foo
then the schema version will be Horde_Foo_schema_info whereas when the components are upgraded from horde-db-migrate the schema table is lowercased: horde_foo_schema_info

that simple commit, make sure that same tables are going to be used when horde-db-migrate and horde-db-migrate-components are used
