Update tests for forced breaks at fragmentainer start.

If there's a forced break, and it's at a valid class A breakpoint, we
may break there. There's nothing in the spec suggesting otherwise.

This is working correctly in the LayoutNG fragmentation engine, but not
in the legacy engine (where we require some non-zero block-size content
to allow forced breaks). Remove invalid tests, and add a couple of valid
ones.
