Speculatively re-enable TouchInputBrowserTest.TouchHandlerConsume

So TouchInputBrowserTest.TouchHandlerConsume was failing somewhat consistently.
However I cannot reproduce the error locally. Nor on trybot runs.

I want to re-enable it on the FYI bot Mojo Android to see if it
still reproduces, or has happened to be fixed.
