Subject: [PATCH] Call clearSettingsProvider before and after test

FakeSettingsProvider requires this method to be called before and after
use. Without this, the settings value or content provider may be cached
statically, so the test will be affected by code accessing settings
before it is run.

Bug: b/116668105
Test: atest FrameworksNetTests
Change-Id: I1480f3f3bbb17791752582a70327bb5c7c348d7c
