Riva overwrite content directory

[JarCz]

If I'm upload file to root path "/" Reva overwrite user content directory with single file. User lost all data.

Steps to reproduce:

cd reva/cmd/reva
echo "Test" >test.txt
./reva --insecure login basic
./reva --insecure upload test.txt /

after this operation directory "/var/tmp/reva/data" has only file "einstein", not directory "einstein"

@JarCz thanks for reporting this. We'll look into it.

Still seen today testing federated shares, reproduced on a local folder.

@ishank011 had actually reverted the fix, because it breaks the sync clients (one needs to be able to upload a file to a folder, not within it, from a sync client perspective).
The solution is discussed at sciencemesh/sciencemesh#108 (comment) and it is to change the reva CLI only, not the server side.
