once we have found a valid password then return it directly, no need to iterate over the rest.

This will look like:
No valid password found for EngineSigner 0x5100…cae4, the following errors were found during testing: {"custom crypto error: invalid AES message", "custom crypto error: Invalid password"}. Make sure valid password is present in files passed using `--password` or in the configuration file.

Removed this, because it is better that the caller handles this error accordingly. Thoughts?

parity_crypto::public::Error doesn't impl Eq, that's why it is converted to a String

Fixes #11521
At startup the
engine_signer(s)are tested that they can signdummy data, previously only zeroes were signed to check this. After switching toupstream rust-secp256k1signing only zeroes doesn't work which this PR fixes.
