This is because JiraProject doesn't implement hashcode, so we can't trust a HashSet to sort out uniqueness. I'm changing this to a HashMap and using the configuration string as key instead.

This patch reduces the duplicated bots and maps one issue bot to one IssueProject. It also solves the SKARA-1618 as a side effect.

But I don't think it is the root cause of SKARA-1618. The `IssueWorkItem#concurrentWith` currently only checks the issue project's name and doesn't check the issue id and repos' names so that these work items can't be run concurrently and some of them will be eliminated (Because the method `WorkItem#replaces` returns `true`).

So I suggest to file another issue to record this patch and solve SKARA-1618 by revising the method `IssueWorkItem#concurrentWith` in another patch. What is your opinion?
