Sample from the prior test failing due to timeout

The sample from the prior test is failing due to a timeout in the CI. It was removed in !949 (merged) to enable development, this issues tracks re-instating it (and fixing it for the nightly tests).

mentioned in merge request !949 (merged)

I'm fairly sure this is due to a bug fix in dynesty (https://github.com/joshspeagle/dynesty/pull/203) interacting with the zero log-likelihood.

Basically, only samples with a larger log-likelihood can be accepted and that isn't possible with the zero log likelihood.

I'm not sure if this is really a meaningful test for dynesty anyway.

I was thinking about the zero likelihood test for the sampler review specification document and I think that most standard nested samplers should fail this test since the likelihood constraint is strictly increasing by definition. This definitely applies to cpnest and nessai and one the exception I know of is multinest since it has an option to relax the hard constraint.

created merge request !950 (merged) to address this issue

As agreed on the development call I have created a MR to remove this from the nightly tests as well.

added Sampling label
