[Web channel] NL v2 fixes

[karntrehan]

• Instead of "सर्वे फिर से शुरू करे" in the hamburger icon option of the chat list, "चैट फिर से शुरू करे"
• Starred messages broken:

• Timestamp issue: Check how previous time stamps also become 4.13 instead of 4.11 / 4.12.
  So ek survey hai Jisme 7-8 responses chahiye user ka
  Agar user ka pehla respond 3.40 PM ka hai and last response 3.43 PM ka hai
  All the responses of the user will show 3.43 PM in the chat details screen.
