Title: Expand st_diff column size of notes table

The text column size of MySQL is 64 kb.
The st_diff column of notes table is serialized. If compressed diff size is over, uncompress will fail. So Note#st_diff will return nil.
This situation raise error when rendering view. (example #5234)

#6106 was not enough to migrate.
