A task helper for recovering UserForm uploads targeting incorrectly migrated folders (from Silverstripe CMS 3)
If your project has not been migrated from Silverstripe CMS 3, you do not need this helper.
Before running this task make sure you have repaired the migrated folders themselves.
To do that you have to run the extra migration subtask (`migrate-folders`).
This task is particularly looking at all UserForm file submissions and checks they are in the same
folder where the particular version of its EditableFileField has been set up to upload it to.
If it finds the file has been misplaced, it tries to move it to the correct folder, but only if
the file has not had any manipulations since the uploading happened (the file Version=1).
If an affected file has a draft, then only Live version will be moved, but the draft will be preserved as is.

This was previously broken in a regression from https://github.com/silverstripe/silverstripe-userforms/pull/575
where the fields themselves could still be toggled, but the jQuery event dispatches for the form steps
were removed. This pull request re-introduces those jQuery event triggers when hiding and showing
editable form fields via display rules.
