setSendReportsAtShutdown(false) causes reports to not be sent

[paulpv]

(Pseudo-related: #375)

My sendReportsAtShutdown is configured to be false.
I am expecting reports to be sent at startup.
But...
https://github.com/ACRA/acra/blob/master/src/main/java/org/acra/builder/ReportExecutor.java#L178
...endApplication is being called before the only thing that I can find that approved reports: https://github.com/ACRA/acra/blob/master/src/main/java/org/acra/builder/ReportExecutor.java#L187
startSendingReports(sendOnlySilentReports, true);

Repro:

ACRA.init(this,
          new ConfigurationBuilder(this)
            .setSendReportsAtShutdown(false)
            .build(),
          true);
Object simulateCrash = null;
simulateCrash.toString();

NOTE: I was setting sendReportsAtShutdown to false because in previous versions of ACRA, crash reports would sometimes fail to sent. I will be leaving this to the default of true, but this sendReportsAtShutdown feature should either be fixed or removed. I would be OK for removing it, as long as sendReportsAtShutdown is at least as reliable as sending reports at start up.
