Internal server error when the package URL does not start with a scheme (eg http://)

[stormi]

The sysdig package in the database has an URL that is www.sysdig.org instead of http(s)://www.sysdig.org.

The package/show page errors out when it tries to build the link to it because it thinks it's an internal route.

Solution : add scheme when none is provided. (+ fix the package but that's another story)
