Fix updating TestExpectations during rebaseline.

Replace code mistakenly removed in r148916

This change https://codereview.chromium.org/13913013/ refactored the code for
updating m_isNormalFlowOnly, into a function that could be reused in several
places, but the refactored code was mistakenly not replaced with a call to this
new function!

BUG=None
