AnalyzeSequences bug due to Genome object

[rfriedman22]

This line of code in AnalyzeSequences raises the following error:
AttributeError: type object 'Genome' has no attribute '_initialized'

The error appears to be because the default value, Genome, is not initialized when the init function is called for AnalyzeSequences and appeared in version 0.5.0. The issue doesn't occur in version 0.4.8.

I'm not sure how to handle the error because constructing a Genome object requires passing in the path to a file, but a file may not always be necessary, e.g. when calling the function AnalyzeSequences.get_predictions_for_fasta_file.

Thanks for finding this bug! I think we should remove these two lines.

        if not self.reference_sequence._initialized:
            self.reference_sequence._unpicklable_init()

Here because it only uses the Genome class and its class methods, not an Genome object, it does not have attribute _initialized and does not need to run _unpicklable_init().

That makes sense! I can fix it and open a PR.
