composer.json autoload causes src dir to be used as fallback directory

[petski]

The current composer.json autoload directive causes Bitpay's src directory to be used as fallback autoload directory. This behavior is caused because the "key"-value of autoload/psr-4/* is "". See documentation at https://getcomposer.org/doc/04-schema.md#psr-4 (grep on fallback).

You shouldn't use this project as a fallback directory as it degrades performance of the application in which you use this package.

Easy to be fixed with this patch:

I can confirm this issue.
