error: Secure Store does not reveal secret key

You can see this "Secure Store does not reveal secret key" at the end.

This happens because --admin for the contract is set to the signer, which is theahaco, which is stored in my macOS Secure Store.

Quick stack trace of relevant lines:

• The deploy logic in stellar-registry-cli calls find_args_and_signers
• find_args_and_signers calls stellar_cli::commands::contract::arg_parsing::build_constructor_parameters
• In the stellar-cli source, follow the logic through, and build_constructor_args eventually calls config.locator.get_secret_key. This is the problem!!! It is trying to get the secret key of the admin param, which is stored in secure store and is, thankfully, not available in plain text. The (very old) get_secret_key logic assumed that all keys were stored as plain text on the filesystem.

This should be included in the fix for signer plugins (we need to verify that this PR considers this situation):
