If anyone figures out a way to get rid of the app and certificate and eliminate any kind of pin, password, or gesture to unlock the phone please post the steps.

It's actually really easy. Just uninstall the app, then go into settings -> security --> and under credentials --> clear all credentials. This is safe because it only removes user installed credentials and it will absolutely remove the greyed out area and required password.
Also it will not remove any data.
I actually was able to complete this without deleting the app (I usually USB tether and hate the lock screen).
Go to Systems Settings > Security and Screen lock > Clear Credentials.
Once this is done, you can then select None for screen lock.
