Summary

Fixes #7438 by removing redundant

Details and comments

This test was disabled wrongly, given that Pull Request 741 in aer was merged and newer versions of aer have been released since.

You're welcome to go through this and sort it out, but I think it might be a little more complex than just removing the skip. I had a very brief go before Christmas, and I think I hit some old code in the ConfigurableFakeBackend that was pretty out-of-date and might need a fair bit of updating. I don't remember 100%, though.

Okay, I shall look into it. Thanks for the update!

• @jakelishman, would you be able to provide an insight to the most recent test fail as I wasn't really familiar with qiskit pulse.
• Besides that, ConfigurableBackend had a parameter version which stood for backend_version. This was overlapping with the version parameter in the BackendV2 and thus was changed to fix previous traceback.

At @javabster's request, I've fixed the merge conflicts that were in this PR in order to have it run its CI again, but I don't know any context. My only comment above was just that I'd attempted to remove the unittest.skip line before and seen some failures (and sorry that I never replied to the question at the time).

It's possible that #9168 could be used instead of this PR, but I don't know the context of either PR, nor of the code in question here.

Closing in favor #9168 . Thanks!
