fix the bug which shows wrong people's name when group is created or when a bill is added
When i created a new group and added my friends, they got notifications that the group had been created by some other random friend in their list and not by me. Same was the case when i added a bill using my android mobile, it showed them that bill with someone else rather than me.

Hey Rishabh – could you email us at support@splitwise.com and let us know (a) your account’s email address and (b) the name of one of your friends that was affected by this bug? We’ve heard of the added-to-group problem (and just released a fix), but you’re the first person to report an issue with adding a bill, and more specific information would help us to chase down the problem and fix it more quickly. Thanks!
