Deflake one of TouchActionBrowserTest

Some of the TouchActionBrowserTests are flaky. I was recently told by
sahel@ that setting speed_in_pixels_s to a very high number will ensure
there is one GSU only and will prevent the flaky. This does work, at
least locally. I have tried the test in this CL locally and it was
flaky without this change. With this change, I have ran this test 50
times without any failure.

This CL does that. Right now there are a few tests marked flaky, this
CL enables one of them first. I will monitor the flakiness dashboard
once this CL lands. If this does solve the problem, we will then enable
more tests.
