You removed these tests, but do we already have any test for a scheme that
contains colons?

Oh, my mistake. isProtocolHandlerRegistered() also needs to check if scheme has
colon. Thank you pointing it out.

-invalid_schemes.forEach(function (scheme) {
-    var succeeded = false;
-    try {
-        window.navigator.registerProtocolHandler(scheme, 'invalid scheme uri=%s', 'title');
-    } catch (e) {
-        succeeded = true;
-    }

-    if (succeeded)

-    else
-        debug('FAIL Invalid scheme "' + scheme + '" allowed.');
-});

 // FIXME: Need to check if this function can return 'registered' and 'declined' states as well.

     var state = window.navigator.isProtocolHandlerRegistered("bitcoin", "valid protocol %s");
