Uncanonicalize URIs before comparing them.

In order to ensure we maintain compatibility, we now configure the
canonical URIs instead of the raw URIs. Correspondingly, we need to
uncanonicalize before comparing them.

Note that we uncanonicalize the configured URI, rather than
canonicalizing the one given to us. This is because the canonicalization
format might change (e.g. add extra parameters) at which point they'll
no longer by equal, but should always uncanonicalize to the same value.
