[#60] Changes about a way for teacher to delete a question during "START_MAKE" status

[chrqls]

This post add a confirmation page. Cancel and back buttons work well for me.

Here is some screenshots:

Confirmation page

The step which does not work for now

But my DELETE request is not accepted by the Smileplug. And I know not why:

• on node side, the console shows this:

Error handling: DELETE /smile/questionview/1.json, Details: 200

• on teacher app, this instruction returns '500'

httpURLConnection.getResponseCode(); // returns '500'

Relative issue: #60
