[PATCH] fdo#38448 No scrolling in mailmerge's create new address lis...

Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/2454

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/54/2454/1

fdo#38448 No scrolling in mailmerge's create new address list > customize

What changes I made:

1. After the address list is edited, the scroll bar scrolls up.
2. If all entries are deleted from the list, the scroll bar scrolls all the way up and is disabled.
3. When multiple entries are deleted, the scroll bar is not reset to match the entries. Therefore, 
I reset the scrollbar in this case.
