Issue:
[FEATURE] Remove special characters from payment attempt ID

### Feature Description

Remove special characters from payment attempt_id 

For some gateways like expresscheckout where attempt_id can be passed as reference to txn, special characters limit the possibility of integrating the apis where such referenceIds are passed in URL and gateway doesn't expect a base64 encoded referenceId in URL. 

### Possible Implementation

replace hyphen characters `-` with underscore `_`
