Missing ModuleHandlerInterface use statement in OpenIDConnectClientBase.php

Problem/Motivation

After Updating module to openid_connect 3.0.0-alpha6, it seems the ModuleHandlerInterface use statement is missing in the file OpenIDConnectClientBase.php.

Steps to reproduce

Update module to 3.0.0-alpha6, play drush commands. Open openid_connect settings, and try to add a client. It crashes with an error requesting the ModuleHandlerInterface is missing in the constructor. It does not crash all the time. In any case, the use statement is missing.
