## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so

your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

This PR aims to remove `BaseControllerV1` usage from
`AbstractMessageManager`. As expected this change affected both
`DecryptMessageManager` (`DMM`) and
`EncryptionPublicKeyManager`(`EPKM`).

Since extension already have wrapper classes for both `DMM` & `EPKM` in
the extension code, we want to keep changes minimal and make these both
classes in the core work like controller but let wrappers sync the state
in their classes as we currently do. You can find the extension PR in
the references below.
