Support key with underscore in jsonpath dot notation

[Morreski]

Hi all,

Thank you for this awesome project. I'd like to report what seems to be a bug => when we want to assert against a JSON key that contains an underscore we encounter an error: the jsonpath expression is not valid

How to reproduce ?

With this assert block:

[Asserts]
jsonpath "$.username" exists
jsonpath "$.user_name" exists

The first assertion works but the second raises an error.

Cheers,

You're right. Thanks for reporting it.
We will fix for the next release.

The _ (underscore) has been added in the dot notation in #285.
