When saving a change in a work package already in fullscreen view the successful update flash message contains a link to open the work package in fullscreen view. This is redundant, I believe.

**Steps to reproduce**

- Edit work package

**Expected behaviour**

- flash message with ‘Successful update’

**Actual behaviour**

- flash message with ‘Successful update. Click here to open this work package in fullscreen view’
