Fix passwords settings crash due to null lifecycle owner.

A change related to lifecycles was reverted some time ago
(I7e6d2e9e6fd363a3afdd3dbab24e7c3b36e9ed29), which caused this to break.

The crash is only seen if an autofill service sets the new Passwords
Activity attr; currently no services do.

Fix: 184077486
Test: manual - check settings page and see no crash
Test: manual - same with work profile added
Test: make RunSettingsRoboTests
