[mudrila]

Description

This PR fixes page reload when navigating between child/parent safe in hierarchy and to safe from search

Notes

It brings another issue, that "Invalid Safe" component flashes for a moment but then immediately proper Safe dashboard shown.

Issue / Notion doc (if applicable)

Testing

1. Navigate to Safe that has at least one sub-Safe
2. Go to the Safe's hierarchy page
3. Click on the sub-Safe card
4. Verify that page is not reloading but just navigates to the proper Safe's Dashboard
5. It is expected that you might see "Invalid Safe" component flashing, but it should be immediately replaced with proper Safe details
