Use the fake users defined by QA in E-Signet mock

[naftis]

Currently the verification after sending the record for review, would probably fail for the E-Signet mock users. Use the mock-identifiers.json for E-Signet as well! You can locally create a similar symlink as mosip-mock (https://github.com/opencrvs/mosip/blob/main/packages/mosip-mock/src/mock-identities.json) to esignet-mock.

Remember to also change the Docker image to copy mock-identifiers.json ( opencrvs/mosip#62 example ) if the file is used in Node.js code.
