[evolution-data-server] String freeze break request (GSettings key summary)

        Hello,
I'd like to ask for a string freeze break approval for bug [1]. Its 
fix adds a new GSettings key with a translatable string:

    Whether the migration of old setting was already done

I do not think the GSettings key translations are that important (with 
compare to other UI visible strings), but I'm rather asking. The bug 
itself also wasn't spot by many users, but it proves a possible flow 
in the code logic, which would be nice to have fixed in 3.16.0.
        Thanks and bye,
        Milan
