icasefs: enhance test to prevent regression by changes in the future

This patch adds steps to test case-folding collision detection on the
revision tree built up in the order different from the one reproducing
issue3452.

This may prevent regression by changes around "copy detection" and/or
"case-folding collision detection" logic in the future.
