Some imagemagick-versions (I tested Ubuntu 22.04 and debian bullseye)
always loose exif data when converting from jpg to webp. So this made
our CI fail now, but even if it wasn't failing before, some pods always
had and have versions which might loose the information anyway. So
having a setting to keep exif information is kinda pointless, if we
can't guarantee that the information isn't lost. Also, diaspora isn't a
photo sharing platform and we don't display exif information anywhere,
so I think we should just always strip exif data (which was already the
default before), as we don't need them.
This commit introduces support for AccountMigration federation message
receive. It covers the cases when the new home pod for a user is remote
respective to the recepient pod of the message. It also allows to initiate
migration locally by a podmin from the rails console. This will give the
pods a possibility to understand the account migration event on the
federation level and thus future version which will implement migration
will be backward compatible with the pods starting from this commit.
