When uploading an image or a pdf content to a course, it was not uploaded. When
viewing it, as nothing was uploaded:
- for image, a default one was displayed
- for pdf, it kept loading for ever
This fixes the problem.
We also add tests checking the upload of a new image and a pdf.
Technical note: The file to upload is converted to base64 when the upload input
is changed and stored in file.data. When the user submit the file, it is that
preprocessed data that is being sent to the server. Following 542cb1dc,
nothing was assigned any more to file.data when the input field was changed so
submitted file was then always empty:
- for image, before this fix, undefined was always assigned to file.data
because the "dataURL" was split in 1 element and the second element was taken
for file.data. The submitted file was then always empty.
- for pdf, before this fix, only the preview was generated and file.data was
not assigned. Before that commit (542cb1dc), the file was read twice, one for
assigning the base64 content of the file to file.data and one to render the
preview. Here we read it only once in base64 to store it in file.data and then
convert it to binary for computing the preview using atob.
