Tasks with due:today don't show in green anymore after update to 2.6.0

#### To report a bug...

After updating to Taskwarrior 2.6.0 tasks that are `due:today` don't show in green anymore. Unless they have a due time that is actually after the current time. This is almost never the case though as by default the due time gets set to 12am.

* What command(s) did you run?
```
$ task add example_task due:today
$ task due:today
```
* What did you expect to happen?
The tasks with `due:today` would show with `color.due.today` which is in green in my case.
* What actually happened?
The tasks with `due:today` show as overdue which is red in my case.

My color settings:
`include /usr/local/Cellar/task/2.6.0/share/doc/task/rc/light-256.theme`
which in turn uses
```
# Due
color.due=on rgb343
color.due.today=on rgb353
color.overdue=on rgb544
```
