fix: verbose call method is broken

[m-schmoock]

The verbose call feature seems broken as the Client will always raise method parameter is required. This RP creates the missing testcases that for now fail by intention.

Note: The verbose syntax is introduced on the projects main README.md and the feature is just not working

Also we might have a bug in the message serializer where nodejs will send a stringified string, mening the payload will have "{...}" quotes instead of {...} which causes the server to complain. Why is the npm 1.0.3 release looking so much different to the sourcecode in this repo??

On line 60 of the Client.js module, there is a ternary expression used to substitute the method argument in as the JSON-RPC request. However, the method argument must be compliant (i.e. must have a properties to defined id, method and params). Based on your findings, it looks like this ternary check is failing... I'll continue to dig and update on this PR.

Added fix in #8 - there was an error in the if statement that @m-schmoock properly detected... closing this PR in favor of #8 as Babel was updated along with Gulp to reference the latest versions.
