Changing the encryption Key renders email settings unavaible with SMTP enabled

[jan-thoma]

Description

If the encryption gets changed for some reason and SMTP with credentials is enabled the email settings can't be accessed in the cp, therefore it's necessary to patch the database manually.

Steps to reproduce

1. Setup SMTP with credentials
2. Change the encryption key
3. Try to to access the cp email settings
