Copying script prints id of distro, not parent distroseries

[Jeroen T. Vermeulen]

The script that copies translations between distroseries, when it preseeds a new distroseries' translations with those from its parent series, prints a line of output like:

Populating blank distroseries X with translations from Y.

Here, X is the child distroseries' numeric id. Y is meant to be that of the parent distroseries ("DistroSeries.parent_series") but the id of its distribution is printed instead ("DistroSeries.parent").
