title: vscode with go extension is confused about the name of an import
body: <p>vscode v1.62.2. vscodego v0.29.0.</p>
  <p>I have managed to confused vscodego.</p>
  <p>I had initially created the app with a particular module name in &quot;go.mod&quot;.  Today I realized I should change the name slightly.  I added two characters to the end of the module name.</p>
  <p>As I have a handful of modules and packages, I had to change the import reference for those packages.  This worked perfectly fine for all but one module.  On the others, when I reentered the module after changing the main module name in &quot;go.mod&quot;, there was an import with a red line under it.  I changed the base module name in the reference to match the new name I set in &quot;go.mod&quot;.  That got rid of the red line.</p>
  <p>However, in one module, something really odd is happening.  Just like the other modules, the line initially had the red line.  I changed the base module reference and saved.  The red line went away, then after a second reappeared, and then I hovered to see the error message.</p>
  <p>This is what it said:</p>
  <pre><code>&quot;voltagems/handlers&quot;
  could not import voltage/handlers (no required module provides package &quot;voltage/handlers&quot;)
  </code></pre>
  <p>To be clear, the original name of the base module was &quot;voltage&quot;.  I changed it to &quot;voltagems&quot;.  Notice that although it says that &quot;voltagems/handlers&quot; is not working, it's saying that &quot;voltage/handlers&quot; (without the &quot;ms&quot;) cannot be imported.  The error message taken on its own is technically correct.  There is no &quot;voltage/handlers&quot; package.  It is &quot;voltagems/handlers&quot;, and even though that's what I'm typing in the import, vscodego seems to think I typed &quot;voltage/handlers&quot;.</p>
  <p>Is there some way to tell vscode/vscodego to reexamine the project?</p>
