calendar: Adjust for evolution changes

When launching the default calendar application, we special-case
evolution to make sure it starts up with the calendar component.

This is currently broken in two ways:

 - evolution changed its .desktop file to use reverse DNS notation

 - as evolution can now be distributed via flatpak, we can no longer
   assume that 'evolution-calendar.desktop' exists when evolution does
   (even though we ship the .desktop file ourselves, it is considered
   invalid if the executable isn't found)
