Yes, changed all 3 appearances of 3.38 to 3.36

That's where I start getting lost. The json file has no reference to 
evolution-alarm-notify

So there is a config-opts for each module. I tried putting the line in
both the libcanberra module and the evolution-data-server config-opts.

Neither location prevents the download attempt for the libcanberra repo
which results in the "fatal: dumb http transport does not support
shallow capabilities" error.

Even after removing the entire working directory ~/flatpak, downloading
the json file and making all the edits to change to 3.36 and
DENABLE_CANBERRA=OFF, the system tries to git the canberra repo
resulting in the aforementioned error before the build even starts.

So it appears that flatpak-builder attempts to pull all the module
repos first, as removing the module declaration from the json file does
indeed skip the pull of the canberra repo and allow the build to
proceed.

As I write this, a gnome-3.36 base version is building.  Once it
finishes, I'll see if making the same set of changes will allow a 3.38
version to build as well.

Thanks for the assist. Guess I need to take some time to delve deeper
into flatpak.
