api method resource_attribute() not correctly handling attributes with string interpolation

[jdannenberg]

Given this resource:

execute "Extract Maven #{version} to #{version}" do
      command "tar xzf #{maven_file} --strip-components=1 -C #{targetDirectory}"
      creates "#{targetDirectory}/bin"
    end

resource_attributes(execute_resource) returns {:name=>"Extract Maven ", "command"=>"tar xzf ", "creates"=>"/bin"}.

The XML at this point looks like this:

<command>
    <ident value="command">
      <pos line="43" column="6"/>
    </ident>
    <args_add_block value="false">
      <args_add>
	<args_new/>
	<string_literal>
	  <string_add>
	    <string_add>
	      <string_add>
		<string_add>
		  <string_content/>
		  <tstring_content value="tar xzf ">
		    <pos line="43" column="15"/>
		  </tstring_content>
		</string_add>

		<var_ref>
		  <ident value="targetDirectory">

		  </ident>
		</var_ref>
	      </stmts_add>
	    </string_embexpr>
	  </string_add>
	</string_literal>
      </args_add>
    </args_add_block>
