outgoing-cred-cmd: delay execution until an email needs to be sent

This can be useful in cases when:

1. outgoing-cred-cmd requires a user action or confirmation (e.g. when
   using pass with a Yubikey or similar smart card that requires a user
   to enter a pin or touch the device when decrypting the password)

2. A user starts aerc frequently, but not all the sessions end up with
   sending emails

3. So the user only wants to execute outgoing-cred-cmd when the password
   is really used, so the user doesn't have to enter pin or touch their
   Yubikey each time aerc starts
