Adding contact without country code forces log-out - potential data loss

[Randall Ross]

Action Taken:
Choose Add Contact from menu, using manual method (i.e. not from Address book)
Fill in Phone Number and Name in resulting fields

Observed Result:
Telegram Welcome screen appears
     "Telegram Welcome to the era of fast and secure messaging"
     "Start Messaging"
- forces me to set up my Telegram account again, as if I'm launching for the first time, need to enter Telegram code (from SMS)
- once logged in again, added contact is not there

Expected Result:
Telegram should add the contact

Environment information
Telegram for Ubuntu (Beta) v 2.0.4.0 (note: This was upgraded from v1)
Ubuntu 15.04 (r303)
Nexus 7 (2013) flo
rc-proposed channel

This needs to be take care of ASAP. Adding a user checks the added phone number, but somehow the callbacks are so tied in that it causes a force log out, which wipes the cache, meaning all secret chats are lost for the user!

Hi, I had same problem today adding contact from Address book, but not from Manual.
Same Telegram version (upgraded from v1 too), Bq 4.5 with OTA 8 stable channel

To those affected - you need to add a country code. The application will now appropriately show you the error message, but you know a workaround. If the phone number is not valid - this caused forced sign out (bug, obviously).

I have experimented this again in versión 2.2.30.0 (Ubuntu Touch OTA-12).
Is it a regresion?
