🐛 Fixed extention missmatching .mp4 as invalid

refs https://github.com/TryGhost/Toolbox/issues/120

- When a file name with an .mp4 extension was passed in it was mistakenly taken as an invalid extension. It is pretty valid!
- Fixing this bug allows for for duplicate file detection when uploading valid valies with extensions containing numbers
- Extensions that consiste only from numbers are still treated as invalid
