Something unexpected happens if the server/version/tag doesn't exist:

OVMS# ota status
Running partition: ota_1
Boot partition:    ota_1
Firmware:          3.1.004-193-g0d5cc93/ota_1/ro2 (build idf v3.1-dev-454-gdaef4b5c May 11 2018 07:58:30)
Server Available:  <!DOCTYPE html> (is newer)

<meta charset="utf-8" />
<link rel="shortcut icon" href="http://api.openvehicles.com/sites/default/files/favicon_0.ico" type="image/vnd.microsoft.icon" />
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" />
<title>Page not found | Open Vehicles</title>

... followed by a couple more pages of html, including:

  <div class="content">
    The requested page "/firmware/ota/v3.1/ro2/ovms3.ver" could not be found.  </div>
Fair enough that it didn't find an update as I'm using my own unique
CONFIG_OVMS_VERSION_TAG "ro2", but it shouldn't mistake the html error
page as a valid result.

Suggested fix:
