Properly clear m_logicallyLastRun to remove use-after-free possibility
https://bugs.webkit.org/show_bug.cgi?id=129489
Reviewed by David Hyatt.
A use-after-free issue was caught in Blink because m_logicallyLastRun
is not cleared when the item it points to is deleted. Clearing it
turns the use-after-free into a segfault, and prevents any future
use-after-frees from happening.
