Fixed node id for policy after coming from an event

[nimrodshn]

Fixed the node_id in the evet_details.haml & _condition_list.haml - 'downcase' causes a number of bugs since the id given is NOT correct and should camelize lower instead.

Scenarios fixed:

• When you click on an event link [In the Events accord in the Control page] and the select a policy and in that policy click on Events you will not be transferred back to the Events page.
• When clicking on a condition in the conditions list [i.e. Container Image Condition etc..] and then clicking on one of the conditions it did not take you back to the relevant condition page.
