• Fix Redundant space for DeleteMethodArgument when argumentIndex=0 #4676

Below case will failed because it will change to "public class A {{ B.foo( 1, 2); }}" which contains a redundant space before the first argument.

    @Test
    void deleteFirstArgument() {
        rewriteRun(
          spec -> spec.recipe(new DeleteMethodArgument("B foo(int, int, int)", 0)),
          java(b),
          java(
            "public class A {{ B.foo(0, 1, 2); }}",
            "public class A {{ B.foo(1, 2); }}"
          )
        );
    }

correct answer: "public class A {{ B.foo(1, 2); }}", no space before the first 1 element.
actual answer: "public class A {{ B.foo( 1, 2); }}" has a redundant space before the first 1 element.

Thanks @ckcd ! Indeed looks better when there's no leading space after removing the first element. I've pushed up a very small change to assume the prefix used previously, with an additional test class that shows when that would help here. With that we're good to merge here.
