Installation under Ubuntu 20.04, 'Annotation sets' error

[pjaskulski]

A couple of problems:

1. Installation under Ubuntu 20.04

• Composer 1 is installed by default on the system, you need to manually install version 2 from https://getcomposer.org
• install php-zip: sudo apt-get install php-zip
• install phpunit: sudo apt install phpunit

only after that you can use the ./docker-dev-up.sh script

2. After selecting Settings from the menu and trying to go to the 'Annotation sets' view, an error appears:

Unexpected exception: Source: Missing name

3. when annotating a document, setting 'Display every sentence separately' in 'View configuration' does nothing,
   the document text is displayed the same way.
