import the module as passed before we look in sys.modules

in I2e291eba4297867fc0ddb5d875b9f7af34751d01, the importer
is importing tokens[0:-1] and then the final token as the name;
this doesn't always work for the two example modules of "xml.dom"
and "wsgiref.simple_server".  import the complete path we will
pull from sys.modules directly.
