Semi-revert "[content] Fix navigation in LockObserver browser tests."

The patch:
https://chromium-review.googlesource.com/c/chromium/src/+/1854901

was reenabling the tests:
- IndexedDBExecutionContextConnectionTrackerBrowserTest.ObserverDedicatedWorker
- IndexedDBExecutionContextConnectionTrackerBrowserTest.ObserverNavigate
- IndexedDBExecutionContextConnectionTrackerBrowserTest.ObserverServiceWorker
- IndexedDBExecutionContextConnectionTrackerBrowserTest.ObserverSingleConnection
- IndexedDBExecutionContextConnectionTrackerBrowserTest.ObserverTwoLocks
- LockManagerBrowserTest.ObserverDedicatedWorker
- LockManagerBrowserTest.ObserverNavigate
- LockManagerBrowserTest.ObserverServiceWorker
- LockManagerBrowserTest.ObserverSingleLock
- LockManagerBrowserTest.ObserverStealLock
- LockManagerBrowserTest.ObserverTwoLocks

on Android KitKat.

They are still failing => disabling them again.
