Prevent "saved" message when edit command aborted

Prior to this commit, the `credentials:edit` command would display a
save confirmation message even if it was aborted via interrupt:

  ```console
  $ EDITOR='ruby -e "sleep 100"' bin/rails credentials:edit
  <Ctrl+C>
  Aborted changing file: nothing saved.
  File encrypted and saved.
  ```

This commit fixes that behavior:

  ```console
  $ EDITOR='ruby -e "sleep 100"' bin/rails credentials:edit
  <Ctrl+C>
  Aborted changing file: nothing saved.
  ```

This commit also applies the same fix to the `encrypted:edit` command.
