This test is supposed to verify that Safe Browsing providers can
be initialized correctly even when a table is not configured
properly.
By removing a table from both google and google4, we ensure that
the test will be meaningful regardless of the stack in use.
Also filter out the console noise triggered by looking for the
update and gethash URLs of the "test" dummy provider.
