YUKI Hiroshi 28ba3b54ad Fixup tree structure after tab move correctly.
Keyboard shortcuts Ctrl-Shift-PageUp/PageDown sometimes broke the tree.
This commit fixes following cases:

case 1:
  * [-] A
    * A-1 <= Ctrl-Shift-PageDown at here
  * [+] B

  then they should be:

  * A
  * [+] B
  * A-1

  but actually:

  * [-] A
  * [+] B
  *   A-1 <= still a child of A!

case 2:

  * A
  * [-] B
    * [+] B-1 <= Ctrl-Shift-PageUp at here

  then they should be:

  * A
  * [+] B-1
  * B

  but actually:

  * A
  *  [+] B-1 <= still a child of B!
  * [-] B
