Improve badge update on request detail page when github issue is resolved

[karelstriegel]

Currently when viewing the request detail the status is checked on github, when it is solved the request status changes to claimable, but the update is only visible when you refresh your screen.

While a developers workflow is

1. solve issue on github
2. view the issue detail -> Right now it shows "funded" not resolved. -> in the backend the platform is aware the you can claim is -> button is updated -> But the badge is not updated, only when you refresh.

should be fixed with #218
