Migrations: delete context objects
These objects represent from 30 to 70% of the rows on the objects table,
based on numbers from a few live instances (single-user, small, large.)

As those pseudo-objects prevent creating objects with those actual IDs,
deleting them is a better solution. This could have happened if an
object used another object's ID as its context.
