Handling of path and pathless patch operations

[mshiels]

Happened to see some wso2 documentation on patch and decided to try the two operations against the reference code and the pathless variation just fails miserably, skipping the patch itself. Is this a known issue, when tracing through the code it just ends up doing a return at some point as something was missing it expected to be set.

pathless { "op": "add", "value": { "nickName": "shaggy" } }

pathed { "op": "add", "path": "nickName", "value": "Tomy" }
