Unable to login with the existing email and different Web3AuthClientId. Error: "factorKey not present"

This issue is related to the concurrent login issue, https://github.com/Web3Auth/mpc-core-kit/issues/115.

concurrently login with new user email (as of latest tkey-core sdk (v9.1.1), the logins will be success without any errors)
log into another coreKit instance with the email used above
it will throw an error which indicates factor key is not present (note: with manualSync:false, it will throw a different error, COREKIT_STATUS.REQUIRED_SHARE which is caused by factor not present)

By following the trace, I found that the error is located in coreKit setupTkey method:

at https://github.com/Web3Auth/mpc-core-kit/blob/master/src/mpcCoreKit.ts#L901, we check the existing metadata with OAuthKey we got from the login
since this is the existing email, there's an existing metadata and we assume this account as existing user
then we continue to the usual steps for the existing user and here, https://github.com/Web3Auth/mpc-core-kit/blob/master/src/mpcCoreKit.ts#L939, we create a hashedFactorKey and validate it by checking the metadata again
however, there's no metadata related to the hashedFactorKey we created above, hence skipping all the later steps and methods including the one which set the factor key
the above will result in unable to login when using manualSync:false and factor not present when using manualSync:true
