Incrementing counter for group info request twice
I just noticed, when we're requesting group info, I see this output:
07-05 12:39:44.503 19900-19900/org.briarproject.briar.android.debug I/HotspotManager: requestGroupInfo attempt: 1
07-05 12:39:45.520 19900-19900/org.briarproject.briar.android.debug I/HotspotManager: requestGroupInfo attempt: 3
07-05 12:39:46.541 19900-19900/org.briarproject.briar.android.debug I/HotspotManager: requestGroupInfo attempt: 5
seems like we increment the attempt
variable twice.
