[tests-only] Adjust steps that try to navigate private links

[SwikritiT]

Description

This PR adjusts the test step that tries to navigate private link, meaning that the navigation process is supposed to be unsuccessful.

The changes made by this PR and how they work

• When a user tries to navigate a private link which they don't have permission to , they shouldn't be able to do so and should be redirected to the login page. When a user with permission accesses the private link then #webContainer should be visible to them and they shouldn't be logged out . But for user trying to access it without permission #webContainer shloudn't be present and they should be redirected to login page. This PR adds that extra check

Motivation and Context

These changes were necessary because previously in steps dealing with tries to we used to check the errors in then and in when step we used to check the behavior of the webUI while trying to do certain operation like navigating private link in this case but we didn't check everything.
Now we want our when step to perform all the task that we perform while actually navigating private link and we want to make sure that the process is unsuccessful at when step, so that we know the cause if that step fails for some reason or starts behaving in undesired manner.
