Fix problem of overwriting envs

[alexander-schranz]

Fixes problem of flex overwriting bundles.php envs.

Fixes #879 which currently breaks @sulu skeleton installation.

Not sure how to fix:

Method getPackage may not return value of type Composer\Package\Package, its declared return type is "Composer\Package\RootPackageInterface"

Trying here to fix: https://github.com/symfony/flex/runs/5509940830?check_suite_focus=true

But still errors this way: https://github.com/symfony/flex/runs/5510160271?check_suite_focus=true

the error message you see here are coming from the mock configuration. So that's unrelated to that phpdoc

I think the right fix is to make it use a RootPackage instead of a Package for this property (but also for the actual value, not just for the comment)

[alexander-schranz]

Thx that seems to fix the tests 👍 Had todo the same for LockArrayRepository in FlexTest.

For backwards compatibility to composer 1.0.2 there a class_exists had to be added.
