PHPUnitLogger calls method_exists on null object

[BlairCooper]

At or about line 814 of PHPUnitLogger.php there is an attempt to get the difference on a comparison failure. If the getComparisonFailure method exists the code immediately tries to check for the existence of the getDiff method on the result of calling the getComparisonFailure method. However, if the comparison failure is not present, getComparisonFailure will return null. This results in a call to method_exists with the first parameter as null.

This results in "_method_exists(): Argument 1 ($object_orclass) must be of type object|string, null given" error being generated and the test case existing immediately.

There should be a check for a null return from getComparisonFailure() before checking if the getDiff method exists.
