edit page has duplicated "view-wizard-controls" in html tags

[Steven]

BUG SUMMARY:
When editing a page, if we inspect the html we can see there are two elements with the id="view-wizard-controls". All id's in html tags should be unique.
We need to fix this either for the form that pop's up when adding a block to the page by clicking on the block menu, or fix it for the modal that contains it.
