title: Current working directory is not a Cordova-based project
body: <p>when running <strong>ionic cordova run browser --verbose</strong> in the root of my Ionic4 project I get the error "Current working directory is not a Cordova-based project.". See the error output bellow.</p>
  
  <p>I noticed the command creates a "www" folder only to remove it again a few seconds later. When I manually add the folder after it was removed (but while the command is still running) I can prevent the error. However the "www" folder will stay empty and the served webpage will say no file found.</p>
