Fixed some details that affected the UX when displaying the move item modal:
- Now it is avoided that when opening the modal the list of items is reloaded.
- Double clicking on the folders inside the modal navigates to that folder.
- Navigating to a folder in the modal does not reload the breadcrumb.
- Do not change the content of the 'move' button.
- Finally, the reloading of the folder list when closing the 'New folder' option has been avoided.
