title: VsTac task failed, could not find file appAsTgz.tgz when using global Cordova toolset
body: <p>When I use my globally installed Cordova 7.1.0 toolset and do an iOS remote build (to simulator or to Local Device), I almost immediately get the error message:</p>
  
  <pre><code>Error   MSB4018 The "VsTac" task failed unexpectedly.

  </code></pre>
  
  <p>I can do iOS and Android browser builds.  I can change the toolset to <code>&lt;vs:toolsetVersion&gt;6.3.1&lt;/vs:toolsetVersion&gt;</code> and the error goes away and the message succeeds.</p>
  
  <p>Is it possible to use the global Cordova 7.1.0 install instead of the VS TACO 6.3.1 toolset and get working iOS remote builds?  This is with Visual Studio 2017.</p>
