Bug Report

SDL crashes in case 'AppStorageFolder' doesn't have read/write permission

Reproduction Steps

1. In case when there is no read/write permission
   for the value of AppStorageFolder in smartDeviceLink.ini
   the SDL crashes in initialization because the
   assertion for the Protocol Handler instance fails.
   The reason for this failure is that Protocol Handler
   is not initialized due to failure of Application
   Manager Init method caused by lack ot r/w permission.

SDL log an error and stop working correctly
There is no any dump
