Incorrect extension detection in case of file-names without extension

[MikiDi]

See

file-service/web.rb

Line 54 in dd42c51

file_extension = upload_resource_name.split('.').last

.
A file named README for example, would result in a triple containing the extension as README, which is incorrect. This should be no triple or an explicit empty value instead.

For files with spaces in the name, this fully breaks the upload. Since the file name is considered to be the extension, the physical file URI will have (unescaped) spaces in it, which causes Virtuoso to crash.

FYI I believe this is fixed in later versions
