Http 412 error when connecting to Bitbucket (BB-7267)

When pushing to Bitbucket, some users may receive the following message:

#!bash

error: The requested URL returned error: 412 while accessing https://sh45park@bitbucket.org/sh45park/android-news-player.git/info/refs
fatal: HTTP request failed

This error message is erroneous and actually should inform the user that they don't have a password set on their account.
