fix(jqLite): fire $destroy event via triggerHandler

in jQuery 1.8.x the data() data structure is changed and events are
not accessible via data().events. Since all we need is to trigger
all event handlers, we can do so via triggerHandler() api instead of
mocking with the internal jQuery data structures.

This fix was originally proposed by PeteAppleton via PR #1512.

Closes #1512
