[flexiglass] Disable SceneContainer when running AlternateBouncerViewBinderTest

Only run AlternateBouncerViewBinderTest if the SceneContainer
flag is disabled.

When the scene container flag is enabled, the
AlternateBouncerViewBinder is not used. Instead, when
the SceneContainer is enabled, the alternate bouncer view
is a Composable (AlternateBouncer.kt).
