I tried to add a credential in Passphrase but get the following error:
Undefined variable: v_is_unlocked
Further investigation shows that Passphrase is trying to read whether or not a credential is locked permanently when generating the form for creating a new credential.
The following is my attempt at a fix:
```diff --git a/src/applications/passphrase/controller/PassphraseCredentialEditController.php b/src/applications/passphrase/controller/PassphraseCredentialEditController.php
