test($log): run all $log tests in IE9 & non-IE9 logging mode (#15995)

In IE 9 console methods don't inherit from Function.prototype and, hence, don't
have apply. Until recently IE 9 logging in AngularJS was restricted to the
first 2 parameters but that changed as we could just reuse
Function.prototype.apply everywhere, creating one code path for all browsers.
Therefore, we can now run all tests in modes where apply exists on logging
methods and where it doesn't.
