Load channel content on remove filter

[AlexVelezLl]

Summary

showLibrary is the method we use to load and show the channels. But if we have filters, it never sets the rootNodes array. The problem was that we were not calling that method again when we removed the filters, so if we had filters in the first render, these channels would never have been loaded.

Code changes make sense, and I have confirmed the fix manually.
