In commit 84940644de, bms_add_range was added with an API to fail with
an error if an empty range was specified. This seems arbitrary and
unhelpful, so turn that case into a no-op instead. Callers that require
further verification on the arguments or result can apply them by
themselves.
This fixes the bug that partition pruning throws an API error for a case
involving the default partition of a default partition, as in the
included test case.
