Do not corrupt URIs entered into the Hyperlink dialog

...by fully decoding them via DECODE_WITH_CHARSET (where charset defaults to
UTF-8) instead of merely normalizing them to IRIs via DECODE_TO_IRI.  For
example, entering

  http://example.com/foo%2Fbar

into the Hyperlink dialog would have resulted in a corrupted URI

  http://example.com/foo/bar
