MNT Ignore narrow no-break space in regex in tests

[GuySartorelli]

I ran framework's unit tests locally with MariaDB 11.4, and got some failures. The failures were a result of having U+202F instead of a regular space in the result. The tests I've updated don't really care what kind of space is used, so replacing the space with \h and allowing unicode matches resolves these problems.

Didn't see any repeats of this problem, so fingers crossed we don't see that in CI either once we make the change there.

I can't replicate this issue locally running 11.4 on a vanilla 5.2 install

Huh. Must be something weird with my setup then.
