In the "View Diff" page, click one line in diff content to open one comment dialog 

and create one comment WITHOUT issue opened. And reload that view diff page, click

the flag of that comment we just created, the "IssueOpened" checkbox is checked in

the dialog. Close it and reopen it again, the checked status is OK.
Since the status setting is missed, we set the issueOpened status and issued status

when creating the draftcomment in the comment block.

Added a unit test, which passes along with all other tests.
Tested with a commentEditor which contains a comment whose 'loaded' attribute and

'issueOpened' attribute are false and the default setting is true. Previously, the

editor's 'openIssue' attribute is true. After, the attribute will set to user's setting

with the patch.
Test for some cases, all passed.
