Add checks for:

• exam tickets on assignments nested in or parent of other assignment with exam tickets
• extended deadline to match the extra time calculated from general start/deadline

Changed:

• Warning message displayed about using discussions with timed assignments

Fix:

• check on generated exam tickets should only consider students eligible for exam (i.e. students enrolled for grade).
