Reland "Update unicode-regexp-ignore-case-noi18n expectations"

This is a reland of c6c9d4bf

Original change's description:
> Update unicode-regexp-ignore-case-noi18n expectations
> 
> There appear to be one or several bugs in noi18n mode such that
> expectations in this test are no longer met. This CL updates
> expectations to the current behavior and re-enables the test so we at
> least preserve coverage in the other cases.
> 
> The behavior in question should be investigated in the future
> (low priority).
