[pgAdmin4][Patch]: To fix database disconnect option

[Murtuza Zabuawala]

Hi,

PFA minor patch to fix the issue where database disconnect option is not
working.

*Steps to re-produce:*
1) Create a "test" database
2) Connect to "test" database
3) Right click on "test" database and try to disconnect it, you will get an
error on console.
