Temporarily turn off Settings CodeInspection test

Something is causing our ClassScanner to find 0 classes in the
com.android.settings class, which causes the CodeInspection test to
fail. This CL temporarily disables these tests to get the tree green
while we further investigate the root cause of the problem.

Bug: 64840107
Test: make RunSettingsRoboTests should succeed
