SCORM and New Window does not work when preview disabled.

Guys,
There is a bug for a new Scorm object fix from https://tracker.moodle.org/browse/MDL-46236 which prevents "New Window" from coming up with the option "Disable Preview mode" > Yes.

Affected code: mod/scorm/view.js
The problem comes from this code:

var mode = Y.one('#scormviewform input[name=mode]:checked').get('value');

where it is undefined, meaning, the browser cannot find the control.
To fix it, I have added a check to find the control before getting the value.

var modeinputexist = Y.one('#scormviewform input[name=mode]:checked');

if (modeinputexist)

{ var mode = Y.one('#scormviewform input[name=mode]:checked').get('value'); if (mode) launch_url += '&mode=' + (mode ? mode : 'normal'); }

For people who encounter "New Window" problem...
