Hooks: Make sure that original task is properly detected

Browse source 
On modify event uses UUID of the original task being modified
to determine which line should be interpreted as modification
of the task.

This was achieved by searching by a substring in a specific JSON
format, which, consenquently, failed on JSON strings of other (valid)
formats.
