Shuto Yano 48b0164676 [InstagramBridge] Fix instagram GraphSidecar output and Video embedding (#1361)
* [InstagramBridge] Fix GraphSidecar output

Fix following issues which related to output of the GraphSidecar type posts.
- The GraphSidecar post's media wasn't outputted except for first picture when searching by hashtag or location
- Video didn't embedded
NOTE:
The function getInstagramStory() which was called when the post type is GraphSidecar didn't seem to work just as one intended.
Because the web request called in that function is just to get the media of single post, NOT to get the media of Story.
But I don't have any idea to solve #694, so it seems be better to rename these function and member variable properly.
