This migrations runs only if the old 20150404193023_participation_counter
migration has not been run.
The new migration is a lot faster, because it runs after the
participation-cleanup migration has been run, so the participation table
is now a lot smaller for people upgrading from 0.5.x to 0.6.x.
It also doesn't remove manually created participations (without likes,
comments or poll participations on the same post).
Fixes#6786
* remove author_signature column
* delete all self-participating participations
* delete all participations where author and post-author are remote
* delete all duplicate participations
* delete all participations without post
* create unique index
Following query takes over 20 minutes and fills up the database:
SELECT * FROM participations WHERE author_id = XXXXX
On servers with a huge participations-table this is a serious
performance issue which is easily fixed by the author_id index

We can determine diaspora_handle from a relation with people for the
shareables (posts, photos). So we don't need to store diaspora_handle in
the DB. Also remove tmp_old_id from photos which is not refenrenced anywhere.
Also:
* remove share visibilities where the shareable is already deleted
* remove share visibilities where the user doesn't exist
* remove `created_at` and `updated_at` to make the table smaller
As according to http://openid.net/specs/openid-connect-core-1_0.html#PairwiseAlg:
"If the Client has not provided a value for
sector_identifier_uri in Dynamic Client Registration
[OpenID.Registration], the Sector Identifier used
for pairwise identifier calculation is the host
component of the registered redirect_uri."
