  tests: refs::crashes: create sandbox for creating symref
  
  The test `refs::crashes::double_free` operates on our in-source
  "testrepo.git" repository without creating a copy first. As the test
  will try to create a new symbolic reference, this will fail when we want
  to do a pure out-of-tree build with a read-only source tree.
  
  Fix the issue by creating a sandbox first.
