Redmine

When updating the non-working days administrative option, extant issues set as "Following" do not have their start and due dates updated to reflect the change in non-working days.

To test:
0. Have the system configured as non-working days: Saturday, Sunday
1. Create an issue to be completed on Thursday.
2. Create an issue that Follows the previous issue, with 0 days' delay (which means that this issue will be done the next day, e.g. Friday)
3. Ensure that in fact, the new issue is correctly set to start and be due on Friday.
4. In `Administration -> Settings -> Issue tracking -> Non-working days` change the setting to Friday, Saturday.
5. Return to the "Following" issue.

Expected results:
The "Following" issue should have its start and due dates set to the next Sunday.

What actually happens:
The "Following" issues' start and due dates have not been updated.

Note that removing the Following relationship and putting it back does in fact set the correct start and due dates (e.g. to Sunday).
