socket listen issue for project-settings

[mohit5540]

• when project-settings component is loaded multiple times, socket listen services are registering same amount of times which is causing multilple publish sites and message dispalys
• to solve this, unregister socket service while component is getting destroyed
• check for vue.js component life-cycle for detailed understanding

[gkumar9]

• As detailed, the problem arises from multiple registering of same socket service. So, to solve it we'll remove the listener( deregister) the service upon Destroy of Component. [ vue cycle ]
• Done, added the code of remove listener. [refrence]
