Parent Tasks double count Estimated Time totals
Description
If you have a bug or feature as the Parent Task of other bugs or features in the same target version, the total estimated time counts both the parent task time (which is derived from the child tasks), and the child task time. For one level of inheritance, this causes double counting. For multiple levels of inheritance, this causes some multiple of counting.
To reproduce:
Create Bug #1
Create Bug #2, call it 8 hours estimated time, and assign #1 as its parent.
Create Bug #3, call it 8 hours estimated time, and assign #1 as its parent.
Any calculation involving total estimated time will total to 32 hours, with 16 hours for Bug #1, 8 hours for Bug #2, and 8 hours for Bug #3. It should total to only 16 hours.
