Add tests for maps with multiple entries.

Previously, the tests did not include maps with more than a single entry
since the iteration order is randomized and the tests only accepted a
single valid expected value.  This commit modifies the tests to accept
multiple valid expected values and adds tests for a multi-entry map to
both Dump and Formatter.
