tersestatus: sort the dictionary before iterating on it
There has report of flakiness in test-status-terse.t. In the terse code, we are
iterating on a dictionary without sorting and since python dicts are unordered,
that can be a reason behind the flakiness. Before we have a better
implementation for the terse thing, let's make sure current implementation
possess minimum bugs.
