HTML export is not showing the SLA values correctly

Summary

When trying to export some SLA values to HTML and if the customer had disabled the Dark feature sd.sla.improved.rendering.enabled to revert the SLA rendering format (as explained here: How To Revert The SLA Rendering Improvement Changes) we got some $remainingTimeHumanReadable displayed as values.

Steps to Reproduce

1. Follow the workaround suggested in this article: How To Revert The SLA Rendering Improvement Changes
2. Try to export some SLA using the HTML export option through the Issue Navigator

Expected Results

The values are correctly displayed as expected.

Actual Results

Some SLA values are being displayed as $remainingTimeHumanReadable

Workaround

Use the CSV export (this will display the SLA values on both formats)
