Fix the writing of invalid environment refssh-fix-environment-write-ref

Environment names that contained a space would cause an error
in GitLab 10.1 because a new guard clause was introduced in
Repository#write_ref to prevent such references from
existing. Use the slug instead to ensure that the name
is valid.

Closes #39182
