Comment(by ericmann):

 This seems like an extreme fringe case - i.e. you'd have to 'try' to break
 things in order to see this happen.  Either way, the only issue here is
 with the text of the message, not with what WordPress is actually doing.

 If you've got your heart set on changing the message, though, you could
 prototype a routine that verifies the plug-in exists after checking the
 version.  Right now, it looks like it's checking against the version
 number stored in the database (lightweight, just a quick options lookup).
 You could change it so that it loads the plug-in header instead and
 verifies the version against that information - if the header loads, the
 plug-in exists.

 This would also prevent the (extreme fringe) case where someone:

  1. Is on the plug-in upgrade page
  1. Updates said plug-in via FTP or SSH
  1. Returns to the upgrade page and clicks on "upgrade automatically"

 The plug-in would already be up-to-date and wouldn't need an update ...
 the system should alert the user accordingly.
