bug#67937: 30.0.50; auth-source-pass relies on epa-file being enabled

[Arsen Arsenović]

Hi there!

It would seem that auth-source-pass relies on epa-file being enabled to
be able to decrypt passwords.

Repro steps:
- emacs -Q
- M-x epa-file-disable
- M-: (auth-source-pass-get 'secret "something")

You will see a GPG-encrypted data string.

epa-file-disable should not break the auth-source.

TIA, have a lovely day.
