Sign-in doesn't call when timer runs out

[Michał Karnicki]

And it doesn't call, because:

file:///opt/click.ubuntu.com/com.ubuntu.telegram/1.1.0.93/telegram.qml:646: TypeError: Property 'calling' of object QQmlComponent(0x1c9e350) is not a function

Steps to reproduce:
1. sign in with phone number, don't input the received code
2. let the timer run out

Expected:
Telegram should call you.

Actual:
Timer stops at 0:00, nothing happens.
