Continued newline into an EOF comment confuses PropertyInstruction

[rcjsuen]

If an escaped newline ends up extending to a comment that leads to an EOF, the parser will think that there are two properties when there should only be one.

import { DockerfileParser } from 'dockerfile-ast';

const content = "ARG var=value \\\n # comment";

let dockerfile = DockerfileParser.parse(content);
let instruction = dockerfile.getInstructions()[0];
console.log((instruction as any).getPropertyArguments().length);
console.log((instruction as any).getProperties().length);
