Added opening <p> tag

Not sure if this originally worked fine in Meteor 0.7.1, but since it's been updated to 0.8 it throws the following error:

"While building package `cordova-phonegap`:
cordova.html:2: Expected "div" end tag
...eviceStatusText}}</p></div>"

due to the opening <p> not being included. Adding it back in to fix this error.
