Closes gitlab-ee#8234

See merge request gitlab-org/gitlab-ce!22764

Paginate Bitbucket Server importer projects

See merge request gitlab-org/gitlab-ce!22825

Fix failing spec in spec/controllers/admin/hooks_controller_spec.rb

attr_encrypted expects models to have their attribute methods defined,
or it will override them with standard Ruby accessors. Migration specs
that rolled back the state of the database after columns were migrated
to encrypted values were interfering with these definitions. To ensure
that the SystemHook specs pass, we need to call
`SystemHook.define_attribute_methods` to ensure that attr_encrypted sees
the right methods that reflect the latest state of the database.
