PushEventPayload.commit_count_for returns sum of bigints

Rails 6.1 represents it as an integer, which is correct

This class has been removed in:

https://github.com/rails/rails/pull/39758

According to the specs description the behavior is correct
now and there is no need in expecting an additional transaction
to be raised

Now select and group statements are taken into
account

Now with 6.1 if no-store is set on Cache-Control
header all other cache directives are dropped

We need to work it around by passing primary key explicitly

A page can be either a String or Hash, but when it's a Hash
it should be passed as kwargs in order to avoid warnings

Within Rails 6.1 there have been a lot of work related to
database and how to make sharding possible. Some methods
have been removed/renamed. Let's comply with those changes.
