New media: Media Library broken after uploading files

[johnbillion]

Steps to reproduce:

1. Make sure you've got some content in your Media Library already.
2. Create a post, hit the 'Add Media' button and upload an image.
3. Click the 'Media Library' tab on the left. Nothing shows up except whatever you just uploaded.

Note that, oddly, if you first switch to the 'Media Library' tab on the left, then switch back to 'Upload Files', it all works as expected.

Noted; I know what's going on here. The request for more images isn't firing off — I'm working on improving the views so this doesn't happen.
