libobs: Fix obs_data crash

Browse Source 
Accessing objects inside obs_datas after obs_data_clear was called on the
parent obs_data causes a NULL dereference.

Reproduce with:
	obs_data_t *data = obs_data_create();
	obs_data_set_obj(data, "foo", NULL);
	obs_data_clear(data);
	obs_data_get_obj(data, "foo");
