confirming the edition of a task yields an empty task

[aravantv]

Steps to reproduce:

1. start the app
2. create a task (say '123')
3. double click on the created task to edit it (say you change it from '123' to '12345')
4. press Enter to confirm the edition

Expected result: task in "non-edited" mode with the label '12345'

Actually observed: empty task

I tried pushing all the versions of the various non-dev dependencies to the latest but it's even worse: the list does not appear at all, only the footer is displayed.
