Fix result shapes

[alecandido]

Currently, result shapes are broken for the QICK drivers, as reported by @JavierSerranoGarcia in qiboteam/qibocal#737

However, it seems like the tests in https://github.com/qiboteam/qibolab/blob/595351782d55a20fa2b8c35104c000092e42f585/tests/test_result_shapes.py are also broken for iqm5q (currently using Zurich, in a pretty weird way.

I'm trying to understand how this is happening, but Qibocal seems properly compensating, since the resonator_spectroscopy routine is then properly working.

Checklist:

• Reviewers confirm new code works as expected.
• Tests are passing.
• Coverage does not decrease.
• Documentation is updated.

Maybe @hay-k could also have an idea, given his work on #797
