- Now that the 'diagnostics' command can detect duplicate UUID
values, it makes sense to incorporate that into unit tests that
employ multiple recurring tasks.
- While fixing bug.360.t, discovered a bigger problem, which is not yet
fixed. When a due date is removed from a recurring child task, the
imask, parent and recur attributes should also be removed. Similarly
when a recur frequency is removed from a recurring child task, the
imask and parent should also be removed.
- Net result: two new failing tests.
- Many tests referred to 'synch_key.data', which is not the correct
name. It should be 'synch.key'. This has no effect on the number
of passing tests though.
- Corrected all unit tests that used the old syntax "task done 1" to
use the new syntax "task 1 done". Similarly, "task 1 ..." is now
"task 1 modify ...".
