elementary Calendar hardcoded when launching dates

[jmgibson1981]

What Happened?

I was purging some packages that I don't personally use. I left the io.elementary.calendar flatpak in place but removed maya. I expected double clicking an event would open my default calendar which is via Evolution. It did not, rather tossing an error about io.elementary.calendar not in $PATH.

Nowhere that I can find is it mentioned that a standard system package is a dependency of a flatpak? And there is zero indication that this was the issue. Solved it by trial and error.

Steps to Reproduce

apt --purge autoremove maya-cal*

try to double click event on right side of drop down calendar on top bar

Expected Behavior

Expected it to open Evolution.

OS Version

8.x (Circe)

Session Type

Classic Session (X11, This is the default)

Software Version

Latest release (I have run all updates)

Log Output

Program ‘io.elementary.calendar’ not found in $PATH

AFAIK there's no standard for opening the calendar to a specific date. We probably should double check how GNOME Calendar and Evolution handle it and see if there's some convention that we can copy.

If not we could fall back to just opening the default calendar by checking if there's a default app for calendar file types. This would be a bit more of a graceful fallback than nothing at all
