Wrangler tests: Return a fake tablet in the wrangler test dialer to avoid tablet picker errors spamming the test logs

Description

The wrangler test framework was incorrectly creating a lot of unnecessary logs like shown below. The fake tablets it creates don't always contain a valid QueryService implementation since the tests don't need it. The tablet picker started logging these as warnings when it was reimplemented resulting in inaccurate logs.

This PR returns a fake queryserivice in such cases so that the picker doesn't log them. Some residual logs are also removed.
