webapp: When adding a new local repository, fix bug that caused its group and preferred content to be set in the current repository, even when not combining.

There was a tricky bit here, when it does combine, the edit form is shown,
and so the info needs to be committed to the new repository, but then
pulled into the current one. And caches need to be invalidated for it
to be visible in the edit form.
