Hi

If you forget to install db schema before you try to add ezmbpaex attribute to User class, you'll get a fatal error when publishing the class.
Well, the schema is wrong so the fatal error can maybe be accepted.

However, what's worse : The whole ezuser table will be truncated. A kinda drastic result after a forgetfulness

Steps to reproduce

Install plain
untar extension
update autoloads
login to admin as admin
Follow the installation manual, expect forget the thing about db schema
edit User class, add expiry attribute
Publish class
mysql> select * from ezuser;
