submodule: check for NULL return of get_submodule_ref_store()

Browse Source 
If we can't find a ref store for a submodule then assume the latter
is not initialized (or was removed).  Print a status line accordingly
instead of causing a segmentation fault by passing NULL as the first
parameter of refs_head_ref().
