Subject: [PATCH] desktop: fix sending files with + in file name (#6836)

* desktop: fix sending files with + in file name

Use RFC 3986 URI encoding (File.toURI()) instead of application/x-www-form-urlencoded
(URLEncoder/URLDecoder) for file path URIs. URLDecoder treated literal + as space,
corrupting filenames containing + on desktop.

* less breaking approach
