Web UI: The referred group does not recognize changes to group name and causes an error

[NickAraujo]

This error occurs when using the end of day group feature, and may be preventable. Here's the context:

1. Create 2 groups.
2. Set the 2nd group as the end of day group and refer to the 1st group.
3. Change the name of the 1st group and try to save. You'll get an error.

If the referred group field recognized the name change to group 1, it could spare users from receiving an error.

Update: The problem is not corrected even after the user re-selects the referred group. This is confusing because, at this point, everything looks correct. The fix actually requires the user to uncheck end of day group and then re-check it and select the intended group.
