Display the avatar of the lockees associated to a vault in the vault list

Currently, I forget who is/are my lockee/s for the sealed vaults. 

If they don't reply, I don't know how to contact via other means to ask them and check their consento app.

And I don't remember if these lockees are busy, on holiday, ... so that it is normal that I don't get a reply yet.
