Hotfix #61 - Clear global arrays on setUp

[michalbundyra]

Fixes #61

As described in #61 in case of request uri contains "phpunit" response is always 404, because request is wrongly created from global arrays with all PHPUnit request data etc.

I think we should clear all global arrays when we run these integration tests.
I'm not sure if it has any impact on current users. All our tests pass with these changes. It would be nice to test it with some applications.

We have to set args (and argv for consistency) because args is checked on constucting console request:
https://github.com/zendframework/zend-console/blob/master/src/Request.php#L43-L48
and here we got before all params passed to phpunit runner.

/cc @Scyt8l3 - would you be able to test that branch with your application to check if all works correctly? Thanks!

Hi @webimpress,
A lot of vendors are using Global arrays to work and this PR breaks a lot of the vendors I use in my project since the the 3.2.1 release.
Can you consider fine fixing the problem instead of clearing all Global arrays (I don't think it is a normal behavior for a php application to be loaded with empty Global arrays)?
Thanks.
