issue: Rename issue-open to issue-open?.

issue-open returns a boolean. So, it makes sense to name it like a
predicate.

* bin/tissue (tissue-list): Replace issue-open with issue-open?.
* tissue/issue.scm (tissue): Export issue-open? instead of issue-open.
(<issue>): Rename issue-open to issue-open?.
* tissue/web.scm (issue-listing): Replace issue-open with issue-open?.
