Title: Fix URL generation when there are no image manipulations specified

Without this patch the URL ruby-thumbor generates has one too many slashes after the signature.

Example of bad url before patch: /Tp9ufQVWNLVkNOwv6zXu5k2oFkc=//my.domain.com/some/image/url.jpg
Example of good url after patch: /964rCTkAEDtvjy_a572k7kRa0SU=/my.domain.com/some/image/url.jpg
