Web Inspector: inspected object wrapper should be released by InjectedScript when popover closes
https://bugs.webkit.org/show_bug.cgi?id=77972

When object popover is shown the object under cursor is resolved and its
wrapper is put into 'popover' object wrapper group. The group is discarded
when the popover closes.
