Add a validation to "JIRA Macro Repair" feature.

Current behavior:

It's only possible to perform the macro fix, but users can't validate neither have visibility of what exactly has been fixed. E.g: Which pages, how many macros and etc.

Clicking on 'Start' will fix all macros without additional information and 'Skip' will bring you to the "Space Import" page.

Desired behavior:

It would be great to have the ability to see what's going to be fixed by the repair assistant before proceeding with the fix.
