Subject: [PATCH] WLFilters: Respect default values

Followup to I3e48a9f2d9b70f0b9f6d7c6329db9c8e8001ee49
Reported in T174725#3590145

Comparing current value and active value with
different representation ("1" !== true) leads to
not applying filters that are ON by default.

Bug: T174725
Change-Id: If083610c0294756589adfc32a59388cc7422ad5d
