#635 Use existing project > copy for working distributed

[Alexander Waldmann]

The "create copy for working distributed. new project name" checkbox in the "select local project" dialog on a participant side after receiving an invitation is redundant, since this does exactly the same as "create new project", except the project name is auto-generated as "projectname-copy".

I would expect this function to:
- merge MY files in MY copy of the project
- with the files from the inviting user
- into a new project

What it does is:
create a project with the configured name with the files from the inviting user. My own local files are not copied.

Maybe this also copies some project configuration, which i didn't notice but this is still very confusing... and should at least be documented better.

The code got broken either by the partial sharing feature or multiple projects.
The code to create a copy is still present but it is currently not used.

Feature got removed.
