removed conflicting check

[GabrielCC]

I'm playing with Treblle and trying to integrate this library.

It seems some work was recently done on the environment check and the current version has 2 pair of checks that contradict themself:

        if (! in_array(\config('app.env'), \explode(',', $treblleConfig['ignored_environments']), true)) {
            return;
        }

this will basically reject all environments, except the ones in the ignored_enviroments

the rest of the check will reject all environments in ignored_environments

fixes #88
