Wiki markup transformation adds extra "\" within info panel

Issue Summary

If you have an info panel with “\” character within it and then you set up a transition screen, the ADF → wiki markup conversion will add an extra “\”. When users then save the wiki markup, the change will be reflected on the adf rich text field.

An unexpected behaviour when using a custom field(Text field-multi-line).

Steps to Reproduce

1. Adding a value to a field custom field(Text field-multi-line);
2. Using the value in the "info panel" inside the field;
3. After transitioning the issue and resolving it the content of the field where it has "/" gets duplicated. 

Expected Results

The text value in the field should be the same after transitioning the issue. No changes should be made to the content of the field by transitioning the issue.

Actual Results

When updating the field using an "info panel" inside the field and using "/" in the text and resolving the issue, the forward-slash "/" gets duplicated.
