Following query takes over 20 minutes and fills up the database:
SELECT * FROM participations WHERE author_id = XXXXX

Add warning about MySQL collation
Fix database index length
This allows new databases to be created with utf8mb4, on MySQL. The maximum
column size is 767 bytes. Each character is 4 bytes long -> 767 / 4 = 191
characters for the column.
URI.extract recognized http:// as an URL, causing invalid
associations. #5347 already fixed the parsing, this just
cleans up the caches to get rid of the false associations.
Add Sidetiq webview to the Sidekiq monitoring panel
Add rake task maintenance:queue_users_for_removal
