BUG#965872: Server crashes in embedding_sjm on a simple 1-table select with AND and OR

Browse Source 
- This is a regession introduced by fix for BUG#951937
- The problem was that there were scenarios where check_simple_equality() would create an
  Item_equal object but would not call item_equal->set_context_field() on it. 
- The fix was to add the missing calls.
