Fix for env_files loading

[wolf4ood]

Hi,
i found out that when loading env_files with profiles , if a profile is not matched the loading process is interrupted and the eventual other files in the list are skipped.

In order to show this behaviour i've created the test set_env_files_for_config_profile_inverse by copying set_env_files_for_config_profile inverting the positions of the two files in the test.

I'm not sure if it's a wanted behaviour or a bug. In case of a bug in this PR there is the fix

Thanks :)
