JPATH_ROOT is not set correctly for tests.

[Achal-Aggarwal]

We are setting JPATH_ROOT in bootstrap as a constant.
<const name="JPATH_ROOT" value="__DIR__" />

I observed that phpunit create a php constant JPATH_ROOT with value __DIR__ not with value __DIR__

[Achal-Aggarwal]

IMO it does't effect tests but it defeats the purpose of using __DIR__.
