Remove the --help separators temporarily.

This will ensure that the latest version of test that claims to support
args 0.12.0 will actually run correctly with that version. After this is
released, I'll re-add the separators and fix the args constraint.

See #396

+* Temporarily remove separators from the help output. Version 0.12.8 was
+  erroneously released without an appropriate `args` constraint for the features
+  it used; this version will help ensure that users who can't use `args` 0.13.1
+  will get a working version of `test`.
+
 ## 0.12.10
 
 * Add support for a package-level configuration file called `dart_test.yaml`.
