  tests: rebase::submodule: verify initialization method calls
  
  Some return codes for functions which may fail are not being checked in
  `test_rebase_submodule__initialize`. This may lead us to not notice
  errors when initializing the environment and would possibly result in
  either memory corruption or segfaults as soon as any of the
  initialization steps fails. Fix this by wrapping these function calls
  into `cl_git_pass`.
