Fixing twisted tests.
It has been observed that when a "twisted" test has "very little" commands in the stack, it uses to fail since the proxied service cannot be reached. This commit puts some delay before the first command gets run by the test interpreter; both in the form of a "blind" sleep, and with a more structured 'wget' loop.
