Fix likelihood count for Dynesty
Dynesty to include the internal counts from the sampler. This fixes the discrepancy between the saved number and the number displayed in the log files as mentioned in #516.
Any calls to likelihood prior to sampling (e.g. from timing the likelihood here) are still included, however, these calls could be excluded if prefered.
I chose to change
calc_likelihood_count over adding something in
_generate_result so the number saved to the result file matches the output of this method to avoid confusion if the user called the method elsewhere.
