Fix scrolling left button inadvertently cancels listtree

Depending on the actual keymap, canceling a listtree with the
"scroll left" button may not be intended, especially
if the list is entered from a completely different focus
(think of leaving a plugin with "long left")

Note:
initializing "scrolling_left" with true without anything actually
scrolling sounds odd to me... maybe this variable should be renamed?
"pgleft_allow_cancel" comes to my mind (with opposite boolean states)
