Fix deprecation warning in ActiveRecord 7.1 when clearing active connections

[haffla]

Hi. Passing no argument to ActiveRecord::Base.connection_handler.clear_active_connections! was deprecated here and produces following log.

DEPRECATION WARNING: `clear_active_connections!` currently only applies to connection pools in the current role (`writing`). In Rails 7.2, this method will apply to all known pools, regardless of role. To affect only those connections belonging to a specific role, pass the role name as an argument. To switch to the new behavior, pass `:all` as the role name.

Rails documentation of method: https://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/ConnectionHandler.html#method-i-clear_active_connections-21

Failing Github actions don't seem to be related to my change.

Hello @haffla ! Thanks for putting this up. We'll have to see what changed out from under us to cause those test failures.

Hi @lancetarn. Were you able to dig into this?

The issue seems to be

LoadError: Error loading the 'sqlite3' Active Record adapter. Missing a gem it depends on? can't activate sqlite3 (~> 1.4), already activated sqlite3-2.0.1. Make sure all dependencies are added to Gemfile.

Rails seems to have had the same issue.
