Fix BigDecimalTest.test_stripTrailingZero.

jessewilson reverted an upstream change (https://issues.apache.org/jira/browse/HARMONY-4623)
that caused an RI incompatibility. Although it seems like the RI behavior is
wrong, the poor design of BigDecimal.equals (which checks both value *and*
scale) probably means we should remain compatible.

This patch changes the test expectation to match the RI's behavior and adds
a comment in both the code and its test explaining that this is deliberate.
