Allow notifies to be sent to the top level includes when they were static

Browse source 
Since we introduced static includes in 2.1, this broke the functionality
where a notify could be sent to a named include statement, triggering all
handlers contained within the include. This patch fixes that by adding a
search through the parents of a handler for any TaskIncludes which match.

Fixes #15915
