✅ ♻️ <amp-ima-video> test is not an AMP element test (ampproject#34230

)

The existing file `test-amp-ima-video.js` is a misnomer since it does not actually test the `<amp-ima-video>` element, only what it loads inside the frame.

Accordingly, rename `test-amp-ima-video.js` as `test-ima-video-internal.js`. Also remove stubs specific to the AMP runtime, since it doesn't run inside the iframe.
