accountsservice is collapsing multiple distinct accounts into one when uid is same

[Scott Merrilees]

$ grep user /etc/passwd
scott:x:1000:1000:scott,,,:/home/scott:/bin/bash
scotti:x:1000:1000:scotti,,,:/export/home/scott:/bin/bash
$

These two accounts are collapsed into just scotti when presented via lightdm.

Ordering in /etc/passwd doesn't change which account is selected, and this ordering is inconsistent with other programs such as ssh which pick the first line when doing getpwuid().

The switch user account menu in the unity panel instead of account name displays "Invalid UTF-8".
