fix(packages): backend was missing uuid package

Due to failing docker builds it was brought to our attention,
that the backend relied on the uuid package without declaring
it as dependency. This worked in all development and build
scenarios as the frontend declares uuid as dependency already
and top-level `yarn install` installs all dependencies from all
workspaces. However as the docker build only runs for either
the backend or the frontend, this failed.
This commit adds the dependency to the backend as well.
