Update path to look for sqlite db

[gavin-black]

Looks like there may be a potential path issue with iOS 7, will update to follow Gordiii's assessment (#37) and then check that everything still works as intended on iOS 6.

Reverted back to using the default ApplicationSupportDirectory after finding issue is caused by missing path, so I added this line to accommodate:

[fileManager createDirectoryAtPath:appSupportDir withIntermediateDirectories:NO attributes:nil error:&err];

Thanks for the update. Plan to revisit everything early January, and will try to incorporate the path fixes you've mentioned.

Hi Gordiii! Thanks a bunch for your interest and contributions in iMAS and this security control. As part of our research, we are always interested to hear about how folks are incorporating iMAS into their production environments. When you have a chance do you mind emailing me directly and tell me about your use of iMAS. Ideally, which industry, type of application, iMAS security controls used etc. My email address is gganley@mitre.org With your feedback, we are hoping to garner enough support such that we can successfully propose and have accepted another year of research funding which means continued support by Gavin and myself. :-)

Was not able to reproduce this on my device, but went ahead and surrounded the persistence store creation logic with a try-catch block. If it fails the original way it retries with Gordii's method.
