frontend: FTBFS rawhide
Fix the test_fork_copr_projects_with_more_builds test by creating new
app context. For F32+ (something changed), per test case failure:
> raise RuntimeError(_app_ctx_err_msg)
E RuntimeError: Working outside of application context.
E
E This typically means that you attempted to use functionality that needed
E to interface with the current application object in some way. To solve
E this, set up an application context with app.app_context(). See the
E documentation for more information.
To allow wrapping already wrapped method, I needed to fix the decorator
to bypass **kwargs as well.
