[Dextrose] [PATCH 4/5][dextrose2][sugar] Dont store activity_id in bundle entry

[Martin Abente]

In older sugar behaviour, installed activities would be removed
when their bundles were removed from journal. That behaviour
is not present anymore either in dextrose or upstream.

Therefore, I see no reason to modifiy the bundle metadata
to add the activity_id anymore. I could not detect how, but 
this operation caused to corrupt xo bundles metadata when
these were created outside journal logic, i.e using dbus
datastore interface.

Fixes #2610
