Nice fix here 😄

I think this will fix the weird problems we've seen! Definitely I know from experience it can write to both directories - and it seems DEFAULT_PHONE_BOOK can change depending on circumstances. I think last time, @MadhaviSeelam had restarted after the file existed and it fixed the issue (it seemed to move the ALL PROFILES to her regular profile after reboot). Specifying the path is a great solution for this! 😄
