[pgAdmin4][Patch]: Fixed couple of minor issues

[Khushboo Vashi]

Hi,

1. When we try to delete the table row with the column definition having
NOT NULL TRUE and HAS NO DEFAULT VALUE then it fails.
    Please find the attached patch for the same. (delete_row.patch)

2. The debugger can not be opened from the View trigger.
    Please find the attached patch for the same. (view_debugger.patch)

Thanks,
Khushboo
