[pgAdmin4][Patch] - RM 4082 - Download CSV error displayed for procedure and functions with create script

[Khushboo Vashi]

Hi,

Please find the attached patch to fix the RM #4082 - Download CSV error
displayed for procedure and functions with create script.

The error message in case of any error while downloading the CSV file was
blank, so now it has been displayed.

Thanks,
Khushboo
