Fix an error of 'Object has been destroyed'

When app is terminate by SIGTERM or tizen.application...exit(),
There comes a TypeError 'Object has been destroyed'

suspend() will be called again on quit() for backgroun-runnable
apps, but since this.mainWindow can be already destroyed, below
code can throw exception with destroyed object 'this.mainWindow'
 - addonManager.emit('lcSuspend', this.mainWindow.id);

It is enough to call setEnable() for suspending (if window is alive)
