fix(prs): Make r/R refresh properly update reviewer status as expected

This change fixes a bug that caused us to not be showing up-to-date status/
state in Reviewers. The fix causes the cached GraphQL client to be cleared
when a refresh is requested — ensuring the next enrichment invalidates the
cache, and then a request for fresh data is made over the network to GitHub.

Otherwise, without this change, when pressing "r" or "R" to refresh, the
enriched PR data (including reviewers) was being served from a
5-minute-TTL GraphQL cache. That meant that if someone approved the PR,
and then we refreshed in dash, the reviewer status wouldn't update.

Also clears the label cache on refresh, for consistency.
