    Issue 4552: Restore features to correct state after disabling field trials

Since then all these features remained disabled by default.

However, one of the features has now been flipped to being enabled by
default: `kLookalikeUrlNavigationSuggestionsUI` cc: @jumde

Since we aren't explicitly disabling any of these features, removed them
from the test.

    Enable Lookalike URLs interstitial by default

    This CL enables the interstitial by default for lookalike domains in
    user's navigation history (i.e. site engagement). Matching with top
    domains is controlled by the topsites parameter.
