title: init.ps1 is not executing (nuget package)
body: <p>My nuget package project is a structured like following (very simple):</p>
  
  <pre><code>- lib
   MyCom.dll
  - tools
   Init.ps1
  </code></pre>
  
  <p>Init ps1's content:</p>
  
  <pre><code>param($installPath, $toolsPath, $package, $project)
  
  $project.Object.References | Where-Object { $_.Name -eq "MyCom" } |  ForEach-Object { $_.EmbedInteropTypes = $false }
  </code></pre>
  
  <p>Nuget spec:</p>
  
  <pre><code>&lt;?xml version="1.0"?&gt;
  &lt;package &gt;
    &lt;metadata&gt;
      &lt;id&gt;***&lt;/id&gt;
      &lt;version&gt;***&lt;/version&gt;
      &lt;title&gt;***&lt;/title&gt;
      &lt;authors&gt;***&lt;/authors&gt;
      &lt;owners&gt;***&lt;/owners&gt;
      &lt;licenseUrl&gt;***&lt;/licenseUrl&gt;
      &lt;projectUrl&gt;***&lt;/projectUrl&gt;
      &lt;iconUrl&gt;***&lt;/iconUrl&gt;
      &lt;requireLicenseAcceptance&gt;false&lt;/requireLicenseAcceptance&gt;
      &lt;description&gt;***&lt;/description&gt;
      &lt;releaseNotes&gt;***&lt;/releaseNotes&gt;
      &lt;copyright&gt;Copyright 2018&lt;/copyright&gt;
      &lt;tags&gt;***&lt;/tags&gt;
      &lt;references&gt;
        &lt;reference file="MyCom.dll" /&gt;
      &lt;/references&gt;
    &lt;/metadata&gt;
    &lt;files&gt;
      &lt;file src="lib\MyCom.dll" target="lib" /&gt;
    &lt;/files&gt;
  &lt;/package&gt;
  </code></pre>
  
  <p>I don't know why init is not setting myCom.dll embed interop to false.
  Same thing happens if I use Install.ps1. </p>
  
  <p>I'm using VS 2015.</p>
