Properly handle HTTP hosted URLs.

Properly handle HTTP hosted URLs.

We used to be storing packages from HTTP hosted sources in directories
named after the hostname. There was no distinction between a package
from an HTTP source and an HTTPS source with the same name. This was
contrary to the rest of pub's logic, which considered those different
sources.

Closes #1418
