Remove string check for 'None' in HTML template

In Jinja, you can use dot notation to check for values.  If a value
does not exist, you get None by default.

* wqflask/base/data_set/dataset.py (Dataset.get_accession_id): Remove
returning a string version of None.
* wqflask/wqflask/templates/correlation_page.html: Delete `!= 'None'`.
