Statistics go missing in phone view

[ialarmedalien]

When viewing offer statistics on a narrow screen, some of the numbers go missing.

Steps to reproduce the bug

1. Go to any profile page, scroll down to the offer statistics.
2. Compare the view with a narrow browser window vs a wide one (or compare phone view to that on a computer).
3. Note that the bottom row (marked >) has one less number than the upper row.

Expected behavior

Both rows should contain the same info.

The fix

...is pretty easy - just ensure that both rows have the same columns set to collapse.

The html should look something like this:

<tr>
    <th></th>
    <th>Total</th>
    <th>Declined</th>
    <th class="collapse">Expired</th>
    <th class="collapse">Accepted</th>
    <th title="cancelled offers as a percentage of accepted offers">Cancelled</th>
    <th title="failed offers, which do not include cancelled, as a percentage of accepted offers">Failed</th>
    <th>Completed</th>
</tr>
<tr>
    <th title="offers received">&lt;</th>
    <td>n</td>
    <td title="n received offers declined">%</td>
    <td class="collapse" title="n received offer expired">%</td>
    <td class="collapse" title="n accepted (estimated)">n%</td>
    <td title="n received offer agreed to cancel">n%</td>
    <td title="n received failed">n%</td>
    <td title="n% of received accepted offers completed, n% of all received offer completed">n</td>
</tr>
<tr>
    <th title="offers sent">&gt;</th>
    <td>n</td>
    <td title="52 sent offers declined">63%</td>
    <td class="collapse" title="n sent offers expired">n%</td>
    <td class="collapse" title="n accepted (estimated)">n%</td>
    <td title="n sent offer agreed to cancel">n%</td>              //  <--- note no class="collapse" here
    <td title="n sent failed">0%</td>
    <td title="n% of sent accepted offers completed, n% of all sent offers completed">n</td>
</tr>
