fix(android): restore local notifications after device reboot

[tntwist]

Hi,
this should fix #2830

Here are the changes I made:

• Saves notification json instead just saving the id
• Adds BroadcastReceiver for restoring local notifications

Please review the changes.

Kind regards

Thank you for your contribution. I tested the changes with the sample app submitted to #2830 by @meltuhamy here https://github.com/meltuhamy/cap-local-notification-persistence-bug. I reproduced the issue and verified the changes fix the re-scheduling of notifications after reboot.

Hey Team,

In what Version of Capacitor that Issue got fixed?
I'm still having the Problem that local notifications get lost after a device restart.

I'm using the Ionic Framework Version 5.4 with:
"dependencies": {
"@capacitor/android": "3.3.3",
"@capacitor/app": "1.0.6",
"@capacitor/core": "3.4.0",
"@capacitor/haptics": "1.1.3",
"@capacitor/ios": "3.3.3",
"@capacitor/keyboard": "1.1.3",
"@capacitor/local-notifications": "^1.0.9",
"@capacitor/status-bar": "1.0.6",
"@ionic/storage": "^3.0.6",
"@ionic/vue": "^5.4.0",
"@ionic/vue-router": "^5.4.0",

Is there anything I need to do to make it work ?

Thanks a lot for your answer.

Update:

I tried the App with local notifications on a newer Android Version 11 and here it works fine also after restarting the device.
On the older Android Version 9 it doesn't work.
