[ENHANCEMENT]: Export Hashlist LineCount

[gpascal123]

Description

Via the RowAction menu of a hashlist, a file can be created with the "Export Hashlist" button. http://localhost:8080/api/v2/helper/exportCrackedHashes Payload: {“hashlistId”:1}

If this file has no lines, the value “null” is entered in the DB column ‘lineCount’ in the “File” table.

It would be good if the backend did not enter “null” here but “0”.
