Resolve workflow option available when issue is already resolved

There is evidently a bug somewhere in JIRA, where the OS_CURRENTSTEP is at 5 ('Reopened') when the issue is at step 5 ('Resolved').

The effect of this is that the global 'Resolve' action is visible. Clicking this (resolving a resolved issue) fixes the problem.

In SQL, issues in this state can be determined with:

create index issue_wfid on jiraissue(WORKFLOW_ID);
create index currentstep_entry on OS_CURRENTSTEP(ENTRY_ID);
select j.pkey, j.issuestatus, c.STEP_ID from jiraissue j, OS_CURRENTSTEP c WHERE j.WORKFLOW_ID=c.ENTRY_ID and j.issuestatus=5 and c.STEP_ID=5;
