Object with an empty string as key getting handled incorrectly

[tmladek]

Consider this object:

{
  "foo": {
    "": {
      "bar": {
        "baz": 123
      }
    }
  }

The following path returns [123], as expected:

jmespath.search('foo."".bar.*', test)                                                                                                                                                                                                 
[123]

However, when I put a wildcard in place of the key which is an empty string, I don't get a result:

jmespath.search('foo.*.bar.*', test) is None                                                                                                                                                                                          
True

This is strange, because if I don't specify the second wildcard, the first one works and I do get a result:

jmespath.search('foo.*.bar', test)                                                                                                                                                                                                    
[{'baz': 123}]

I've asked on gitter and have been advised this might be a bug and not my misunderstanding of the JMESPath syntax.

I'm on JMESPath version 0.9.4, installed by pip on Python 3.
