It remembered pull request filters

That's a nice feature to have, but currently it somehow remembered pull request filter (https://github.com/johanmynhardt/trello4j/pulls?q=is%3Apr+is%3Aclosed) and keeps redirecting me there from the corresponding issues page (https://github.com/johanmynhardt/trello4j/issues)

Start by reproducing the redirect from the GitHub issues page after visiting the pull request filter URL in the issue body. Inspect the extension's navigation and filter-state handling entry points; done means the issues page no longer redirects to the remembered pull request filter while filter state still behaves as intended.
