[CM1-627] Add popup window when Multiple outcomes are available

As a CaseMate user I want a popup informing me if I have multiple outcomes available (multiple signed Do:s with Outcomes) when I press the Outcome tab

Because it is good if the system helps me to choose the most suitable outcome option.

Notification popup has been added.

The Do outcome list will populate directly and there is no need for Save in order to populate the list.
