Use TMDB namespace prefix in psr-4 autolaoder

[MarkRedeman]

Using an empty namespace prefix is bad for performance, see composer validate --strict.

👍 absolutely right :-), I just did a check on that composer validate --strict command but for me it just outputs the json file is valid but has a few warnings ( however it doesn't show any? ).

That's strange. For me it showed,

./composer.json is valid, but with a few warnings
See https://getcomposer.org/doc/04-schema.md for details on the schema
Defining autoload.psr-4 with an empty namespace prefix is a bad idea for performance

Btw you can also use composer validate --strict -A, which will validate all your dependencies (which is how I initially saw the psr warning :)).
