AppSpectorSDK 1.4.6 exception being thrown on app start

[willk37]

There are times when launching our app that it crashes on start up. The issue seems to be related to AppSpectorSDK 1.4.6, I could not reproduce the issue on 1.4.5. This particular stack trace is from running a UI test that consistently crashes.

Invalid type in JSON write (NSError)
