Non-encrypted custom fields show as "Encrypted" on a non-admin user

[SBriere]

Expected Behavior (or desired behavior if a feature request)

A non-encrypted custom field values should be available for edition to a non-admin user.

---

Actual Behavior

Currently, when creating a non-encrypted custom field, only admin users are able to edit their values (except for lists, which seem to be working correctly)

Values can be correctly seen in the asset list view or when viewing the asset details, but not when editing (field is grayed out and shows "ENCRYPTED").
