Release Note: Generated payrolls to show once payslip PDFs are created

There are times when users generate payroll, payrolls are generated first and then PDFs are queued up. Users would have to refresh the payrolls page for Payslip PDFs would be generated.

We now have enhanced the payroll generation to include generating the Payslip PDFs in the background first before it shows all payrolls are generated on the payrolls page. This is to avoid the confusion that the payslips are not yet generated:

Note: No changes on the user interface. The enhancement happens on the background when generating payrolls.
