Disable tests which require cross frame access (same origin)

Disable tests which require cross frame access (same origin)

Several co19 tests assume that the result of window.open will be a window
(instead of a cross frame window), and try to perform illegal operations
on it.  These are already disabled for dart2js.  For dartium, these were
(incorrectly) working because of https://code.google.com/p/dart/issues/detail?id=20143 .

This CL disables these tests for Dartium.  Depending on the resolution of
https://code.google.com/p/dart/issues/detail?id=20146 , they may later
be enabled.
