Disabled AndroidWebView.testScrollToBottomAtPageScaleX0dot5 test.

This test doesn't work under virtual viewport pinch-to-zoom since it
assumes window.scrollTo() moves the virtual viewport.

This one test is busted by turning on virtual viewport. If it's ok to disable
for now, please add a PST OWNER.

[+mkosiba] who's the owner of WebView scroll/pinch paths.

Marcin, for some context, we're planning to finally turn on the new pinch model
described in
https://docs.google.com/a/chromium.org/document/d/1KewSqexq4Pd99RUFB-yVoUIJoc...
for M40.  The "outer viewport" is the only one visible to JS in this new model
and it's always sized to the width of the document (and the height of it is the
aspect ratio of the screen times that width).  For that reason it's not possible
for JS to scroll a pinched viewport to the absolute bottom.  This is by design
so that the effects of pinch are entirely hidden from sites not designed with it
in mind.

For the CC <-> Java delegate API, we can maintain the same behavior as before
though, by combining the inner and outer scroll offsets in the value given to
Java.

For this test, it seems like it should probably be changed to use input events
rather than the JS call.
