Opening composer with Protonmail using URL scheme is not working anymore with 1.16.1

[jumantet]

here is the patch I made and which was working with the 1.15.0 version meaning, the openComposer was properly opening protonmail on compose view with all the options filled, now the protonmail opens well but not anymore the compose view. It is working well with all the other mail client.

Here is my patch :
