Disable ActionRunnerTest.testTapElement on Win Debug.

This test is crashing on the Win (dbg) bot on the
chromium.webkit waterfall; the test was added in
https://codereview.chromium.org/323833003/ and
has never run successfully, so this may be exposing
a real bug. Disable it temporarily to green up
the tree while we investigate.
