uni/cache.t: Fix to handle regex compile time Uni props

Future commits are planned to move the resolution of Unicode properties
from regex execution time to compile time.  By moving the code into a
BEGIN block, this .t can now handle both types.  Before this patch, it
wouldn't show any activity at all if things are done at compile time.
