Remove bug in error reporting

[JeanLucPons]

This bug fix error reporting when wrong lattice element was passed.

  File "/operation/common/miniconda/envs/jlp-py312/lib/python3.12/site-packages/pyaml/lattice/simulator.py", line 427, in get_at_elems
    raise PyAMLException(f"{name} not found in lattice:{self._cfg.lattice}")
                                                        ^^^^^^^^^
AttributeError: 'Simulator' object has no attribute '_cfg'

to:

    bpm_elt = self.get_at_elems(bpm)[0]
              ^^^^^^^^^^^^^^^^^^^^^^

@JeanLucPons @gupichon the smoke test is failing, I don't think this is related to this PR, so I will merge. Is this a known issue?

No this is link to my previous comment, that dt4acc is using BESSY2 example in pyaml directory.
It should use example working with fixed backend release.

There should be no pyaml_cs_oa.controlsystem.ConfigModel anymore in the latest release. So maybe it is just using an old release and the version can now be updated?

A ._cfg was still there is pyaml simulator. No problem, for the moment, with pyaml-cs-oa.
