When you go to the "Earliest" contributions of a user and then go to the "previous 50" until you're at the
start, it counts wrong. So normally when there are less then 50 edits left and you click on "previous 50" you
should be at the 50 most recent contributions. But there is again a button "previous 50" because he jumps not to
the beginning but to the beginning plus 1.

Example: a user has 52 edits and clicks on "Earliest", he gets his edits 1 to 50. When he now clicks on
"previous 50" he should get edits 3 to 52 but gets 2 to 51 and has to click again on "previous 50" to get edits
3 to 52.
