Web SQL Database - rollback test

This code creates a table called 'foo' and inserts a single row. In a separate transaction, it drops the table then tries to insert in to the table 'foo' - obviously failing. That failure should cause the transaction to rollback, and leave the table 'foo' intact. The next transaction tries to select a row from the 'foo' table. If the rollback succeeds, you should see the status change to 'found rows'.
