mistake: Update git-init.sh - check staged file instead of working file
Previously, test would only check the working directory for the encrypted vault.
This allowed an edge case where the following could occur:
- Unencrypted vault is added to staging.
- Vault is encrypted, but is not added to staging.
- Commit succeeds, storing the unencrypted vault.
The new test improves the old by checking against the staged file, instead of the working file.
