Summary

When adding recipients to a mounted store, their keys are not exported into the .public-keys directory of the target store.

Steps To Reproduce

0. (Optional: set GOPASS_HOMEDIR and PASSWORD_STORE_DIR to point to empty directories to avoid interference from existing configuration and stores)
1. Create a new root store : ./gopass init
2. Create and mount a new substore : ./gopass mounts add -c substore ./substore
3. Add a recipient to the substore : ./gopass recipients add --store=substore SOME_KEY_ID
4. Observe that the key has not been exported into the substore : ls ./substore/.public_keys

Expected behavior

Public keys are exported into the .public_keys directory of the target store.
