features_override_module_component_overrides can return FALSE

I am seeing the following warning

array_filter() expects parameter 1 to be array, boolean given in features_override_get_overrides() (line 93 of sites/all/modules/contrib/features_override/features_override.export.inc).

This is caused by features_override_module_component_overrides returning FALSE, which it shouldn't (according to its documentation).
