Incorrect role after accessing a public link with Uploader role

[gmgigi96]

The role in the scope set by reva in a public share link is incorrect when created with Uploader role. It is editor, but should be uploader.
I think this is due to the fact that in the publicshares auth manager. the only permission checked is InitiateFileUpload and assigned an editor role, while the correct check should be:

• if InitiateFileDownload and InitiateFileUpload are set => editor role
• if only InitiateFileUpload is set => uploader role
