Crash with "Harfbuzz version too old" : update Electron

[JulioJu]

Hi !

When I run Mobster on Arch Linux, I have the following error:

$ ./Mobster-0.0.48-x86_64.AppImage
Bail out! Gtk:ERROR:../gtk/gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /org/gtk/libgtk/icons/48x48/status/image-missing.png: Unrecognize

It seams that Electron should be updated : see https://github.com/electron/electron/issues/20348#issuecomment-542150507

Thanks in advance!
