Contractor is GIGO

Passing invalid URIs, e.g. file paths that are not URI-encoded and/or not prepended with file://, prints no errors but produces invalid results:

* In single-uri (%u) contracts every second parameter isn't passed to client.
* In file contracts (%f and %F) the parameters are not passed to clients at all.

This is the behavior of http://www.valadoc.org/#!api=gio-2.0/GLib.AppInfo.launch_uris and Contractor does not perform validity checks before passing parameters to it.
