Adding a feature to a goal immediately after creating the goal causes crash

[Stacey Beard]

Problem

When creating a new goal, the concern has to be closed and reopened before using the new goal. If a new feature is added to the goal immediately after creating it, TouchCORE throws an error and the back button (top-left <) disappears.

Steps to reproduce

1. Open a concern.
2. Create a new goal for the concern.
3. Immediately open the new goal and add a feature to it. TouchCORE will throw an error and the back button will disappear.
4. Re-launch TouchCORE and open the new goal. New features can now be added without a problem. Note that closing and re-opening the concern is generally sufficient to prevent this issue (before trying to add a feature to the goal).

Actual result

Expected result

Goals should be immediately editable without reopening the concern.
