Ensure id present for all Greek public bodies

[rufuspollock]

@okfngr just noticed that in #43 PR a lot of public bodies were missing a key field (now called id).

Would it be possible to generate and add an id field to all records - an id field is required and is necessary for the frontend to work.

We also seem to be missing jurisdiction codes (which are required) for

gr/dpa
gr/adae
gr/asep
gr/esr
gr/synigoros
gr/minedu
gr/neagenia
gr/gsae
gr/culture
gr/gss
gr/gsrt
gr/minedu
gr/minedu
gr/minedu
gr/gak
