Sample App has error counter and command counter reversed

[jphickey]

Describe the bug
The SAMPLE_ReportHousekeeping function reports the error count and command count values reversed.

To Reproduce
Send a NOOP command, then report housekeeping, and see that the error count is in place of the the command count.

Expected behavior
The error count and command count should not be reversed.

Code snips

Inside SAMPLE_ReportHousekeeping(), it has:

    Sample_AppData.SAMPLE_HkTelemetryPkt.sample_command_error_count = Sample_AppData.CmdCounter;
    Sample_AppData.SAMPLE_HkTelemetryPkt.sample_command_count = Sample_AppData.ErrCounter;

System observed on:
Ubuntu 18.04 LTS 64-bit

Additional context
Actually discovered this when writing the unit test for the ReportHousekeeping function (#8), and the test case failed because the counters were backwards.
