fix: Stop reloading events after rotating screen

[anhanh11001]

Details:
I add tags on loading events (RELOADING OR INITIAL LOADING). The events' list is only loaded again if the tag is RELOADING or INITIAL LOADING + the event list is not loaded before.

Fixes #1295

Is swipe refresh works fine?

[anhanh11001]

@liveHarshit yes, it works because I put the tag RELOADING.

rootView.retry.setOnClickListener {
            val isNetworkConnected = isNetworkConnected(context)
            if (eventsViewModel.savedLocation != null && isNetworkConnected) {
                eventsViewModel.loadLocationEvents(RELOADING_EVENTS)
            }
            showNoInternetScreen(isNetworkConnected)
        }
