And fix a statusBar bug

This reverts commit 5e35aa8c.
Merging all epg data on current input item isn't a great idea as,
outside event handlers, we can't really guess which one is related
to our current program. It also allocates extr metadata.
We'll need to store that epg data in a different place.

Sure, this will be unpopular, and this will likely kill you kittens, but
maintaining 2 http interface is stupid and counter-productive.
Let's hope luahttp will finally get fixed.

"sub-source" was formerly "sub-filter", and now the "sub-filter" configuration may contain sub-filters or sub-sources configurations.
so if sub-filter configuration was provided but the sub-filter chain creation was failed, try to use the configuration as a sub-source configuration.
