Empty OR clause with table.delete() produces invalid SQL

[Christopher Monsanto]

See attached test case. Results from running the script:

Expected: DELETE FROM test
Got: DELETE FROM test WHERE

• Fixed bug where :meth:.Table.update and :meth:.Table.delete would produce an empty WHERE clause when an empty :func:.and_() or :func:.or_() or other blank expression were applied. This is now consistent with that of :func:.select. fixes #3045
