[WIP] Fix tests

Tests are absolutely not working for me, so I'm trying to fix them. Let me know if you have any issues/suggestions/etc.

- [x] Morph - Seems to assume temporary files are made, which is not the case I've seen. Simplified so that the morph test passes.
- [x] getterIdentify - photo.JPG tests have incorrect attributes tested for. 
- [x] `lost.png` does not exist. @aheckmann is this image meant to be lost?

There are still 12 pending tests, so there may more that I need to fix.
