Auto DND fix - Remove Do Not Disturb mode

Basically this app reverse the DND effect to normal mode.

Some custom OS has problem -> they automatically enable DO NOT DISTURB mode and then user don't receive any notification or call. This bug is specific for some device and it still exist for Yu Yureka Plus (On custom OS).

**** Auto Repair ****

Now the main functionality is this app also work in background mode, when OS automatically enable DND then this app will automatically disable it. So you no longer have to worry about DO NOT DISTURB mode. DND Fix will handle background work and this app won't drain your battery as it designed for automation and tested on large amount of devices. This app only gets triggered when DND mode triggered by OS.

Ready for open suggestions. For improvements.
