mediawiki.special.upload: Show an error message on "|"

This change prevents that "|" is interpreted as title separator and
shows the following message when the title contains a "|" character:

  The requested page title contains invalid characters: "|".

Before this change the following message is shown on this case:

  The requested page title is empty or contains only the name of a
  namespace.
