After scanning a tag, pushing the home button and starting the app again: the app is created again and not resumed

[FrancescoFreder]

Hello,
i have an issue on my nexus 7 with android 4.2.2 using the last versions of phonegap (2.5.) and phonegap-nfc (0.4.1). when using the homebutton, the app is recreated again and not resumed. but the other state is still there and available as soon as i exit from the application (as if it is started twice). i've broken this down using only the reader demo. this problem only occurres if a tag is scanned.

I can reproduce it with phonegap-nrc-reader-demo in that way:

• starting the app
• scanning a tag (without this task the problem does not occur)
• pushing homebutton to leave the app in the background
• starting the app again

you can the on the logs that the app is created (see logs below). if you exit the application now, the application is still available with the old data).
