#2047 Using test feature on a directory gives errors for non archive files

[Tal Tamir]

In 7z v16.04 x64 on win10x64.

7z has a "test" function that can be used on either a single archive, or a batch of them. This includes selecting a directory in which case all subdirectories will be searched for files and all files tested.

The problem is if a directory contains both archive files and other files (for example, loose jpg files). 7z will report every single non archive file as a corrupt archive.
