Prevent call of self::getClient when not in static context

[robertfausk]

...cause it will break when PantherTestCaseTrait is used in a class
which implements and uses getClient with object context.

This maybe-issue was introduced with:
b9225b0

In my specific case I have a method in object context wich will break my test application:
https://github.com/robertfausk/mink-panther-driver/blob/master/src/PantherDriver.php#L62

This method is always static isn’t it?

[robertfausk]

If a class is using the PantherTestCaseTrait and implementing

public function getClient()

then this method of the implementing class will be called.

E.g. following will result in an error:

public function getClient()
{
    $this->doSomething();
}

Ok got it. If you both import PantherTestCaseTrait and not import WebTestAssertionsTrait because you already defined getClient it breaks.
