Make Debug impl of Uri developer friendly

Previously an assertion like:

  assert_eq!(Uri::parse("some/path"), Uri::parse("other/path"));

resulted in a panic like:

thread 'uri::tests::example' panicked at 'assertion failed: `(left == right)`
  left: `Ok(Uri { scheme: None, authority: None, path: [[115, 111, 109, 101], [112, 97, 116, 104]], query: None, fragment: None })`,
 right: `Ok(Uri { scheme: None, authority: None, path: [[111, 116, 104, 101, 114], [112, 97, 116, 104]], query: None, fragment: None })`'

This commit changes the Debug impl to be more developer friendly:

thread 'uri::tests::example' panicked at 'assertion failed: `(left == right)`
  left: `Ok(Uri("some/path"))`,
 right: `Ok(Uri("other/path"))`'

Fixes #3.
