Epic Name Field is not cleared when changing issue type to Story using Inline and Edit Button Method

Summary

Epic Name Field is not cleared when changing issue type to Story using Inline Method

Steps to Reproduce

1. Create an Epic
2. Change the issue type to story inline (using the pencil icon). or Use the Edit Issue Button

Expected Results

The Epic Name field should be cleared as it is no more an Epic

Actual Results

Epic Name Still Exists.

From what I have noted, this might not necessarily show up in the issue screen. But if you go to the issue navigator and have the Epic Name Column, you will notice that the issue still has the Epic Name Field however, the value might be hidden from the issues screen.

Use the Move option to change the issue type
