v2.30.0: Merge branch 'jul/test-psc' into 'master'

• Add forward compatibility for the decryption of padded data.
• Phone number verification method can now be used with session token.
• setOidcTestNonce() is available to test the new verification flow without requiring any end-user action.

Offline mode

No connection to Tanker remote services is made if not necessary, this is true when:

• The user already exists
• The device is already registered
• The operation can be completed using the device's local cache

Any user registration, device verification, group operation, new encryption or decryption of resource not in cache will open a new connection.
