[MERGE][IMP] website_slides: improve the frontend UI for slide_channels

PURPOSE
---------------

Add small improvements to the frontend UI for slide_channels.

SPECIFICATION
-----------------------

Current behavior before PR:

1. We can't display all uncategorized slides of a course.

2. When you upload an image or PDF, the name field is replaced by the filename even it was filled before selecting the file. This leads to rewrite the name a second time before uploading the slide.

3. There is no way for the website designer to choose if he wants to display or hide the promoted slide of a course.

Desired behavior after PR is merged:

1. Slides without a category are displayed correctly, now you have access to the link "View all" which allows the user to display all uncategorized slides with a possible pager.
You have also the possibility to create a section/category with the new button "Add a section" next to the button to upload content.

2. When you upload an image or a PDF, the name field is no more replace automatically by the filename. Now, it's replaced only if the field is empty when you select the file.

3. Now, there is a new button under the Customize tab to display or hide the promoted slide on the courses. By default, the promoted slide is displayed on the course.
