Failing to render the jira macro results from time to time

My first suggested solution to remove the empty/null ID parts in the JIRA macro was mostly to have a quick fix with an easy and fast upgrade path for xwiki.org that doesn't require a full XWiki upgrade or a manual patch.

That's definitely the easiest and we/I can do that easily by just removing

id.add("");

from the createId() method.

However, we need a JIRA for platform too, so that the removal of empty segments is done at the level of AbstractBlockAsyncRenderer#createId() or even beyond (simplest) and then later move to a HASH for ex.
