Regressions? Glitches/crashes when initial picker display includes contacts #48

This had been working before, but as of tonight (using the master branch), when our picker is set up to contain contacts during the initial display of the view which contains it, they do not display properly. I suspect this may be due to the new approach to handling an empty prompt. Indeed, a quick test confirms that these problems go away if I leave the prompt at its default value of To: but occur when setting it to the empty string.

With a single contact present, the picker appears empty. But clicking on the right edge of the picker places the insertion point to the right of where the invisible contact should be. Trying to click on that invisible contact places the insertion point at the beginning of the line (leftmost edge of the picker). And trying to backspace over the invisible contact results in a crash:

Can you try with the latest develop branch and let me know if the issue still occurs there? I need to cut a release to master and CocoaPods, I'll go ahead and do so if we can confirm the bug is fixed there.
