Resolved NullPointerException causing a blank screen on an ionic app #5

The NullPointerException caused a blank and unresponsive screen (after the splash screen) on a Nexus 4 API 27 emulator. This simple change resolved the issue.

I was using the SecureStoragePlugin in an authguard and forgot to catch the error for when there is no item. The same code worked on iOS so I thought it was a bug, my mistake.
