Usually when you see this error with an initializer, it means that 
initializer was removed upstream but since we consider these as 
configuration we need to manually remove those in debian package. So 
you can just check the source package and see if the initializer is 
still present and if not just remove it.

rm 
/usr/share/gitlab/config/initializers/mysql_set_length_for_binary_indexes.rb

Sometimes our test environment does not have these initializers from 
very old versions so we miss removing them in the maintscripts.
