Fix deeplink when app is suspended (#812)

* Update Navigation.tsx

Missing If statement within the Deep Linking function that broke the ability to change state to hometab

* Updated the function correctly, I missed a bracket

* format

* add pre-existing home state when unspecified path

* Remove unnecessary log
