[TIMOB-17226] iOS: Email Dialog barColor does not work

Problem Description

The barColor is not working (even if it shows the specified color at the begin of the animation, at the end will switch to gray).

Steeps to reproduce

1. Create a new mobile project (classic titanium) 2. copy the code into app.js

var vE = Ti.UI.createEmailDialog({
		"subject" : "Hello Hou",
		"toRecipients" : ["lou9@gmail.com"],
		"barColor" : "#E5E4E2" //does not work, still defaults to system built-in color
});

vE.open();

3. Run the test in the ipad simulator.
