stat()/file_exists() always returns on non-existent files with AWS adapter

[tsmgeek]

When using stat()/file_exists() methods when backend is AWS v3 adapter you always get either true or stat results that are all 0.

If backend is local then these issues do not happen.

Ok so I think the problem is twofold

• if you get a literal FALSE back from getMetadata() it will normally mean it does not exist, the method itself does not throw exception
• if you did a test for has() first you can check if it really exists before you do getMetadata()

The root stems from if you have 'disable_assert' enabled on the Filesystem.
