Application ID is not set

[ammgws]

Describe the bug:
#3354 introduced setDesktopFile (

openshot-qt/src/launch.py

Lines 191 to 195 in 87c07f1

	try:
	# Qt 5.7+ only
	app.setDesktopFile("org.openshot.OpenShot")
	except AttributeError:
	pass

) so that the application ID (such as app_id in Wayland) is set to "org.openshot.OpenShot" instead of "python3". However on my system this is never set despite Qt being >v5.7 as noted in the comment in the code.

Steps to reproduce the behavior:

1. Run openshot-qt
2. Check application ID (for sway Wayland compositor: swaymsg -t get_tree) and see that it is set to "python3"

Expected behavior:
Application ID is set to "org.openshot.OpenShot"

System Details:

• OpenShot Version 3.0.0
• Operating System / Distro: Arch Linux

Log Files:

NOTE: While debugging I modified the try-except with a print statement that you can see at the end of the logs:

Unable to setDesktopFile

It appears that the method was renamed from setDesktopFile to setDesktopFileName
