refactor(morphdb): use the client's constructors now that they are callable

MorphDB.Client 0.5.1 adds [SetsRequiredMembers] to Filter and OrderBy, so
their constructors compile. The object initializers here were working
around that, not expressing a preference.

Verified against the published package, not a local build.
