What It Does

When imperative initialization errors occur while in daemon mode, the errors now come back to the client terminal window.

How to Test

1. With the current functionality, without daemon mode running, if you try to install a plugin that does not exist, it will display 404 errors.
2. With the current functionality, with deamon mode running, if you try to install a plugin that does not exist, it will not display those errors.
3. With the updated functionality, with daemon mode running, you will see the 404 errors appear.
