dynamic_dynesty requires nlive_init to be specified

Hi there,

I recently decided it was time to update my version of Bilby. I made a clean environment and installed Bilby 1.4 (which came with dynesty 2.0.3) and the dynamic_dynesty sampler no longer works.

To make sure it wasn't my code, I tried the example script gaussian_process_george_example.py in the repo, just changing the sampler to dynamic_dynesty (on line 118) and the script fails with the following error:

15:34 bilby INFO : Checkpoint every check_point_delta_t = 600s

15:34 bilby INFO : Using dynesty version 2.0.3

15:34 bilby INFO : Resume file outdir/gaussian_process_george_example_resume.pickle does not exist.

15:34 bilby INFO : Generating initial points from the prior
