Error with "empty" params

[benkeil]

if you have a URL like /Search?&partnerid=12345 the plugin creates two entries: partnerid and an empty one.

"params"=>{
    "partnerid"=>"12345",
    ""=>"",
}

Empty entires must be removed.

Although the example Url might not be RFC conform (I dont know), one does not have control about the Url executed/called by the user. +1 for a fix to not run into the same issue while using the parser.
