[cmv3] HTML Code Hints are not displayed on "<" key

[redmunds]

Typing "<" in an HTML file does not show code hints. Typing Ctrl-Space does not pop them up either.

If you type a char (e.g. "i") then press Ctrl-Space they are displayed.

To @RaymondLim. It looks like in CM v3, the HTML tokenizer flags an unclosed start tag as an error, which confuses HTMLUtils.getTagInfo(). Need to update it to deal with this case.

Fixed in cmv3 branch. Also fixed a HTMLUtils test failure in collecting attributes from an invalid html tag.

@RaymondLim -- we're doing pull requests for changes in the cmv3 branch (you just need to switch the base branch fo cmv3 when making the pull request). Please have someone familiar with the code review the changes in your commit (looks like it's baab037) just to make sure. Thanks!

I looked at the commit and it looks good. Confirmed that bug is fixed. Tested around it a bit and didn't find any other problems. Closing.
