Issue "on hold" is still open issue

Hi, I believe, that issue which is "on hold" should still be visible in "open issues" as it is not resolved (and is probably waiting for something)

Way to reproduce:

1. Create new issue
2. Use workflow button to set it "on hold"
3. Return to issues
4. From "Open","My issues","All" select "Open"
5. You don't see your issue
