[@nativescript/background-http] packagename - illegal argument exception

Issue Description

Hi guys,

When I try to use your background http to upload a file,

I noticed I am getting :
Exception java.lang.RuntimeException: Unable to create service net.gotev.uploadservice.UploadService: java.lang.IllegalArgumentException: You have to set namespace to your app package name (context.packageName) in your Application subclass at android.app.ActivityThread.handleCreateService (ActivityThread.java:5086) at android.app.ActivityThread.-$$Nest$mhandleCreateService at android.app.ActivityThread$H.handleMessage (ActivityThread.java:2428) at android.os.Handler.dispatchMessage (Handler.java:106) at android.os.Looper.loopOnce (Looper.java:226) at android.os.Looper.loop (Looper.java:313) at android.app.ActivityThread.main (ActivityThread.java:8757) at java.lang.reflect.Method.invoke at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run (RuntimeInit.java:571) at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1067) Caused by java.lang.IllegalArgumentException: You have to set namespace to your app package name (context.packageName) in your Application subclass at net.gotev.uploadservice.UploadServiceConfig.getNamespace (UploadServiceConfig.kt:74) at net.gotev.uploadservice.UploadServiceConfig.getBroadcastNotificationAction (UploadServiceConfig.kt:234) at net.gotev.uploadservice.UploadServiceConfig.getBroadcastNotificationActionIntentFilter (UploadServiceConfig.kt:248) at net.gotev.uploadservice.observer.request.NotificationActionsObserver.register (NotificationActionsObserver.kt:31) at net.gotev.uploadservice.UploadService.onCreate (UploadService.kt:194) at android.app.ActivityThread.handleCreateService (ActivityThread.java:5073)

This is because in this file:
https://github.com/NativeScript/plugins/blob/main/packages/background-http/index.android.ts
line 30, we pass in the Utils.android.getApplication()
but the inner method is looking for Utils.android.getApplication().packageName, whereas we get the packageName by Utils.android.getApplication().getPackageName() which can be null/empty, not sure if this is a bug?

Reproduction

1. uploadFile
2. close the app and reopen
3. app crash.

从 packages/background-http/index.android.ts 大约第 30 行开始，查看传入 Utils.android.getApplication() 的位置，并将该值与报告中描述的包名访问方式进行比较。重现 uploadFile、关闭并重新打开的流程；当应用不再因 namespace IllegalArgumentException 崩溃时，即表示完成。
