Fix 'Missing newline before ")"' when no params

[jlmd]

Fix an issue where the Exceeded max line length rule is always trying to put parameters on separate lines, even when there are no parameters, causing the rule Missing newline before ")" to break.

Fixes #327

@jlmd just to confirm - you've tested this is still broken on 0.30.0? @shyiko addressed #327 for that release, so just want to make sure this is an update to that commit.

[jlmd]

@shashachu yes, I tested it on 0.30.0 and is still broken. I'm not sure what the fix of @shyiko does, but for sure it doesn't fix #327 issue. Maybe the issue was not clear enough, that's why I created the PR.

Do you think it makes sense to revert in this PR that commit (b6f9ad5), since it seems that it doesn't really fix any issue? Even the tests that he added pass by removing the condition that he added.

[shashachu]

Let's wait a day or so to see if @shyiko responds about what his original change was meant to do.

[shyiko]

@jlmd is correct (b6f9ad5 should be reverted)

[shashachu]

Awesome thanks for confirming, @shyiko. @jlmd why don't you also revert that commit then.

[jlmd]

Cool! Thanks @shashachu and @shyiko . I've reverted that commit in c24eb5a

[shashachu]

Thanks for the PR!
