The aggregateExpression () JQL function doesn't consistently show results

ScriptRunner's aggregateExpression() JQL function is not consistently showing results in the issue navigator. This bug might be more likely to occur if certain apps are installed, e.g Elements Connect or The Scheduler.

Steps to Reproduce

1. Create a Project with some Issues. Input some estimates in them.
2. Install The Scheduler or Elements Connect plugin
3. Go to Issue Navigator and use the aggregateExpression() JQL function. Example:

   issueFunction in aggregateExpression("Original estimate sum", "originalEstimate.sum()", "Time spent sum", "timespent.sum()", "Remaining estimate sum", "remainingEstimate.sum()")

Expected Behaviour

The aggregateExpression() JQL function displays the results

The Scheduler plugin is disabled

Actual Behaviour

The aggregateExpression() JQL function does not display the results

The following error is shown in the browser console:

The Scheduler plugin is enabled
