Force restic to ask the password when adding a key.

Browse Source 
As `restic key add` uses the same `ReadPasswordTwice()` as the
rest of restic, it is sensitive to the environment variable
RESTIC_PASSWORD or --password-file= override.

When asking for the new key, temporary remove these 2 overrides, forcing
the password to be asked.
