Fix API documentation related to `/source/{project_name}...` endpoints

Refactoring source controller

It's not an action

It's not an action

It's only used in SourceProjectController and SourceProjectMetaController.

It's not an action

It's not an action

This is not an action but called from an action, so make it private.

Don't ignore notifying ActionView::MissingTemplate

Introduces token operations on project

... GET /source/{project_name}/_project/{file_name} API endpoint

.. the GET /source/{project_name} API endpoint

No need to put 2 lines into an extra method.

Also: projectlist, packagelist and filelist are no actions. Only index is an
action...

Handle statistics result returning nil

The backend statistics return no results (nil) in some corner cases.
We better use `blank?` than `empty?` to cover both empty array and nil.

Email for Appeal

Redirect to login page or root if anonymous

When we return an ActionView::MissingTemplate exception, we developers
want to be notified. This way we can fix the exception.

Fix database_consistency TODO file

Remove warning comments about using VCR (II)

We already know how to develop using VCR. No need to include a comment
on tests which use VCR.

Implement notifications for reported request events

[src/api] Update flipper-ui 1.1.1 → 1.1.2 (patch)

The notification contains the reason because the request was reported
and the link pointing to the reported request.

Add missing content moderation events to the notifications for reports

Add missing model annotation for Event::ReportForRequest

This was generated while running `bundle exec rake db:migrate` on
master.

Add migration after flipper rubygem update

[src/api] Update rubocop-rails 2.22.2 → 2.23.0 (minor)

Upgrading the flipper rubygem to 1.1.2 version, requires running a
migration. This migration can be created through the following command:

`rails generate flipper:update`

Add this migration, as resulte of running the command above, instead of
requiring a manual intervention of OBS administrators.
