[TIMOB-7356] iOS: build.py - Console error and no build on first attempt when importing clean iOS project with no iphone folder in project/build/

While using Studio 1.0.7 we started noticing the occasional first attempt to build iOS projects failing and the following text in console: [INFO] One moment, building ... [INFO] Detected missing project but that's OK. re-creating it... This condition is caused by a lack of a build/iphone folder in the project which prompts the message from builder.py. The missing folder is created, and the second attempt should rebuild. We have not seen this error prior to 1.0.7. The only way I have been able to reproduce this situation so far is by importing a project and trying to build. This project presumably had no build/iphone directory builder.py snippet starting at line 655:

starting in 1.4, you don't need to actually keep the build/iphone directory
if we don't find it, we'll just simply re-generate it
if not os.path.exists(iphone_dir):
	from iphone import IPhone
	print "[INFO] Detected missing project but that's OK. re-creating it..."
	iphone_creator = IPhone(name,appid)
	iphone_creator.create(iphone_dir,True)
	sys.stdout.flush()

Steps to reproduce: 1) Import a project into Studio with no build/iPhone folder 2) Attempt to run in simulator Result: Build fails with error in the console Expected: If missing a folder, make it and build
