Ensure locker is unlocked in certain actions

[satazor]

Description

The storage is encrypted with the locker secret, which is great. Nevertheless, when performing certain actions, such as when updating the profile, we should guarantee that the locker is unlocked. The reason is that it might be easy to an attacker to to obtain a reference to the current instance of the idmWallet and start messing around with it. Along the way, we might need to make every instance sealed with Object.seal.

This is somewhat related to #190
