Disable auto-testing of TB2 tests on Chrome
Disable auto-testing of TB2 tests on Chrome

Chrome has started auto-updating even though auto updates are
disabled on the test machines. TestBench 2 works with Chrome 41 (latest)
but opens the test in a new tab instead of in a new window and therefore
is unable to resize the browser to the correct size for screenshots.
