Peter Serwylo 0d4d160407 Fix migration for DB version 50.
The migration resulted in a query being run which was broken. The query
was broken because it was dynamically generated by Java code. This Java
code resulted in a valid migration when until very recently when the
query was refactored to deal with a new DB structure. Now the query is
no longer suitable to be run against a DB_VERSION 49 database.

To resolve this, the migration now hard codes the query to a string
which is executable when the DB_VERSION is 49.
