Subject: [PATCH] Update wipe-tests example to latest API

The `src/effects/Openshot Wipe Tests.py` was no longer usable since
the code was way out of date with respect to the current libopenshot
APIs. This updates the code to execute properly.

(Also: Output the frame numbers on a single line, instead of one per
line, for readability.)
