fix: Enhance test stability in drive_tests.js

In the drive_tests.js file, I improved test stability by introducing
steps in two test cases: "test drive to external link" and
"test drive enabled by default; click link inside data-turbo='false'."

The added  calls ensure that the respective elements (e.g., "#drive_enabled_external"
and "#drive_disabled") are present and visible before interacting with them, reducing the chances of
element unavailability issues during test execution.

This resolves test failures where elements were not immediately accessible, leading to test timeouts.
