solved: /sidekiq cannot be displayed after updating to rails 5.2.4.1

Actual behaviour

An error page may be displayed when accessing /sidekiq after updating to rails 5.2.4.1.
At that time, the following error is output to the server log:

NoMethodError (undefined method 'public_id' for #<String:0x00007f86d1decce0>):
vendor/bundle/ruby/2.6.0/gems/actionpack-5.2.4.1/lib/action_dispatch/middleware/session/cookie_store.rb:111:in 'write_session'

This seems to happen if you have a logged in session when running on rails 5.2.4, update to rails 5.2.4.1 and access with that session.

The problem was solved by clearing the web browser session and logging in again.

Steps to reproduce the problem

1. Log in while running on rails 5.2.4.
2. Update to rails 5.2.4.1 without logout the session, restart and access again.
3. I got this error.

Specifications

Mastodon master branch e0c2ecb or later
