[ruby/rexml] Message less confusing error to human (#16)

• Message less confusing error to human

• Problem: Following error message is not helpful, because you have to reason
  that '' actually means it's in the top-level, and the 'div' (not '') is
  an end tag

    require "rexml/parsers/lightparser"
    REXML::Parsers::LightParser.new('</div>').parse
    #=> Missing end tag for '' (got 'div')
  

• Solution: add a special case in error handling just to change the error message

    require "rexml/parsers/lightparser"
    REXML::Parsers::LightParser.new('</div>').parse
    #=> Unexpected top-level end tag (got 'div')
  

• Refactor by removing unnecessary md check

• Thanks @a_matsuda to review this at asakusa.rb!
