fix(reactor): fix reactor initialization on CLI tools

[glevco]

Motivation

There was a regression in one of the latest refactors related to reactors. The get function is being called in CLI tools instead of the initialize one, which would be correct.

Acceptance Criteria

• Change get_global_reactor() to initialize_global_reactor() on CLI tools.

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
