Quoted keys are obliterated in cast to string

[catskul]

Despite the fact that jsonpath respects quoted strings on query execution, printing the quey loses data where keys are quoted.

In [48]: str(jsonpath_rw.parse('$.foo.derp.herp'))
Out[48]: '$.foo.derp.herp'

In [49]: str(jsonpath_rw.parse('$.foo."derp.herp"'))
Out[49]: '$.foo.derp.herp'

In [50]: str(jsonpath_rw.parse('$.foo."derp.herp"')) == str(jsonpath_rw.parse('$.foo.derp.herp'))
Out[50]: True

Expected output of of the equality comparison should be False
