Description of problem:
In a view with deleting messages hidden, when deleting more than one message, by selecting more than one message and leaving the tree cursor at any position other than the very first selected message, the cursor ends up at the same numerical index rather than being adjusted for the removed messages.

This happens irrespective of sorting order.

Version-Release number of selected component (if applicable):
evolution-3.6.4-2.fc18.x86_64

How reproducible:
All the time, starting yesterday.

Steps to Reproduce:
1.Make sure View->Show deleted messages is disabled
2.In a folder with lots of messages, click on the top message
3.Now shift-click on the second message or, equivalently, press Shift+DownArrow
4.Delete those messages (e.g. Ctrl+D)
5.Note new position of cursor, i.e. which message remains selected.

Actual results:
The cursor is positioned at the same location as before the deletion (the second message).

Expected results:
The cursor position should have been adjusted to take account of the deleted messages, and the first message should have been the current one.

Note that if the cursor is placed at the expected position prior to deleting messages, all appears normal.  For example: click on the second message, then shift-click on the first message, and delete them.  The cursor is now on the first message as expected -- but only because the cursor was already in the correct position.

Additional info:
This seems to be a distinct problem from bug #789984 (in which the correct message is selected but the scroll position is incorrect) which I have *not* seen.
