All applications except for Jupyter have the same #set_initial_status,
so create a new shared example which we include in all application specs
except for juptyer_spec. Juptyer specs already have specs for it's
version of #set_initial_status

This makes this consistent with :updated. And also avoids a potential
issue where an install errors which means that that the recorded version
won't necessarily reflect the version that is actually installed.

Note: updating version column after :updating is not ideal in the
updating -> update_erroed case. This will mean that the application now
records the version as the version that failed to upgrade, not the
version that it is currently on.
