l0ng-ai 89ffde304b fix(plugins): read the marketplace index on first open (#1378)
On a fresh install, Settings › Plugins › Available showed no marketplace plugins until the user refreshed by hand: opening the page asked for the listing without a refresh, which only returned the cached index, and a first run has none. The listing now reads the index when none has been read yet; later opens keep using the index already read, and an explicit refresh reads it again.
