[Core] Master/Slave: mediafiles are visible

[Michiel.Schok]

When an asset contains multiple mediafiles, and one or more of those mediafiles are master/slaved to another application, it is possible to perform an [get] /asset/{id} call in the slave app.

Regardless of the individual master/slave setting on the mediafiles, ALL of the mediafiles are visible in the /asset/{id} call. The mere visibility of one of them is enough to show them all.

e.g. when looking at NIBG content which contains (sometimes) .sami mediafile, we see 4 mediafiles, while only three of them have a master/slave relation.

2.1 release

[Michiel.Schok]

I removed the aut_app ACLs on mediafile PqdlNc?6t8ALzGYqmLmbXMPUn

An /asset/18611 now shows 3 mediafiles (correct),
An /asset/18611/mediafile show 4 mediafiles (not correct)
I'm not able to play, download or view details of the fourth mediafile (correct).

[MC-arjen]

/asset/{id}/mediafile was originaly forgotten. This patch also implements the same behaviour as /asset/{id}

[Michiel.Schok]

Test: OK
3 mediafiles on a /asset/{id}/mediafile
