Grainformat: Extra newlines between comments

[phated]

When two comments come after one another, grainformat will add extra newlines between them. This is a problem because it breaks graindoc.

Here's an example:

/**
 * Some graindoc documentation
 *
 * @param foo: bar
 * @returns foo
 */
// TODO: We need to do something
let baz = foo => foo

In the above example, formatting the code will insert an empty line between the graindoc comment and // TODO comment. Graindoc only works if it is on 1 (or 2 because of annotations) lines before the definition.

Confirmed it still does this, working to fix.
