fix: snowflake imports issue fixed (appsmithorg#34745)

## Description


This PR fixes the intermittent issue in snowflake, where if we import
the app containing snowflake and if we open the datasource it in edit
mode, password field was not there.

Root cause:
When we are on slow 3g and when we don’t wait for datasources to load in
reconnect dialog and quickly go to application, the authentication
object does not get set, which causes snowflake password conditions to
break and it does not show up.
We tried by simulating slow 3g on all environments and were able to
reproduce it

Steps to test:
- We can try importing following app json and simulating slow 3g in
network tab
- Once app is imported, when we see reconnect modal, quickly click on go
to application before the datasources are loaded in the modal
