WPT: Fix contain-style-counters-004.html with correct expectations.

contain-style-counters-004.html has spans as non-siblings of the
div that prints the number.

This patch adjusts the expectations to print 0, instead of 20. Note
that contain-style-counters-003.html already tests for siblings
relationship.
