vertical scrollbar spacing not properly accounted for when state first changes

[Michael Rooney]

https://sourceforge.net/forum/message.php?msg_id=5796050 provided a patch that handles scrollbar spacing better, but it doesn't work if the need for the scrollbar changed in that call, since a layout hasn't happened yet and it doesn't know about the requirements.

To reproduce, switch from an account with enough transactions to warrant vertical scrollbar, then go to one that doesn't. The space on the right will still be there, until you click that same account again. This can also be reproduced by searching in a large account for something that returns a few (or zero) results; it should take up the remaining space in this case.
