This commit fixes some issues in the BackendV2Converter class around its usage wrapping BackendV1 based simulators (such as Qiskit Aer with the current release as of this commit 0.11.x). The BackendV2 converter was incorrectly handling some edge cases in Target creation with simulators that have ideal gates. The first issue was that the handling of ideal gates without any properties was incorrect and could not handle gates that took > 1 qubit. This has been corrected so the converter will work as expect. The second issue is the `online_date` field in the `BackendConfiguration` is optional and may not exist, especially on simulators which that field never really applies for. With these fixes the BackendV2Converter can be used to wrap BackendV1 simulators. Fixes #9562 Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> (cherry picked from commit 789707c)
