newTiddler macro breaks if template doesn't include text

[mahemoff]

config.macros.newTiddler.onClickNewTiddler will break if:

• there is a "template" parameter which references a tiddler containing no HTML control for tiddler text
• there is a "text" parameter

The problem is apparently this:

  if(typeof text == "string")
    story.getTiddlerField(title,"text").value = text.format([title]);

story.getTiddlerField(title, "text") is returning null if the template happens to not include a "text" field.

(This arises for me because I am not allowing general users to change the text, which is simply a couple of macros.)

Added extra condition on "if" clause to guard against this
