Projects with "type": "zip" are extracted to a subpath, breaking devfiles

See original GitHub issue

Describe the bug

Since https://github.com/eclipse/che/issues/14206 is resolved, Theia can handle projects downloaded as zips. However, typically zips (e.g. from github) unzip to a folder including the branch name, which causes the project to be unzipped to a subpath – e.g.

/projects/console-java-simple/console-java-simple-master

instead of

/projects/console-java-simple/

This breaks many devfile commands that depend on the project being in a known location.

Che version

nightly

Steps to reproduce

Start a workspace using the devfile
