The call to LaravelSlack::__construct() has too many arguments starting with config('laravelslack').
This check compares calls to functions or methods with their respective definitions.
If the call has more arguments than are defined, it raises an issue.
If a function is defined several times with a different number of parameters, the
check may pick up the wrong definition and report false positives. One codebase
where this has been known to happen is Wordpress.
In this case you can add the @ignorePhpDoc
annotation to the duplicate definition and it will be ignored.
This check looks from parameters that have been defined for a function or method, but which are not used in the method body.
