Typo in composer.json causes update to fail

[chrisdempsey]

I attempted to install silverstripe-email-helpers to a project I inherited using the require command from readme.md.

composer require markguinn/silverstripe-email-helpers:dev-master

This fails with error

In RootPackageLoader.php line 160:

  require-dev.phpunit/PHPUnit is invalid, it should not contain uppercase characters. Please use phpunit/phpunit instead.

This is due to a typo in the current composer.json file in the remote silverstripe-email-helpers repository at
https://github.com/markguinn/silverstripe-email-helpers/blob/master/composer.json

Line 19 is

"phpunit/PHPUnit": "3.7.*@stable"

but should be lowercase

"phpunit/phpunit": "3.7.*@stable"

I tested this working locally by running composer update on a new project containing only the composer.json below.

Can anyone confirm this and update the github repository?

I don't think I can update the project I inherited until this is available due to the autoload and lock features as it seems likely that manually uploading the vendor directory created with the JSON below would cause a critical conflict?
