Limit issues scope to project context

Before this patch, issuefy all-mighty-under-the-hood powers
were causing troubles to big redmine instances, due to the
system-wide subject uniqueness requirement.

Therefore, since this version, issuefy scope will be
limited to the project where its being used. This means,
issues can be created, updated and related whithin the
same project only.
