I agree with Sebastian Paluch. Here is a patch without tests.

I've added the test-code for Go MAEDA's patch(#28409-1).

Setting the target version to 4.2.0.

I found a problem in patch #28409#note-1.

Redmine shows estimated hours for a parent task in some cases even if estimated hours is disabled. You can reproduce the problem with the following steps:

1. Set any value to the estimated hours field of a parent task and subtask
2. Disable the estimated hours field for the tracker
3. Open the parent task. The value of the parent task's estimated hour should not be displayed because the field is disabled, but both the parent's estimated hours and total estimated hours are displayed
