   ### Jira
   
   - [X] My PR addresses the following [Airflow Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references them in the PR title. For example, "\[AIRFLOW-XXX\] My Airflow PR"
     - https://issues.apache.org/jira/browse/AIRFLOW-5518
   
   ### Description
   
   - [X] Here are some details about my PR, including screenshots of any UI changes:
   If a connection is parsed from a URI (for example if it's overloaded through an environment variable), the schema is the path or the URI.
   
   This is wrong because then the HttpHook uses the schema to prefix the base_url. It is particularly visible when using https, which gets transformed to default http. As a result the URLs are built with HTTP instead of HTTPS.
   
   I propose the following, which it is consistent with what happens when a connection is added through other ways (UI and config files):
   At the Connection level, in parse_from_uri(), implement a special treatment for http connection to have conn_type='http' and schema=scheme
   
   ### Tests
   
   - [X] My PR adds the following unit tests :
   3 new tests in test_connection_from_uri_with_path, targeting HTTPS. I also changed the pre-existing tests with HTTP URIs to indicate that the schema is HTTP.
   
   ### Commits
   
   - [X] My commits all reference Jira issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "[How to write a good git commit message](http://chris.beams.io/posts/git-commit/)":
     1. Subject is separated from body by a blank line
     1. Subject is limited to 50 characters (not including Jira issue reference)
     1. Subject does not end with a period
     1. Subject uses the imperative mood ("add", not "adding")
     1. Body wraps at 72 characters
     1. Body explains "what" and "why", not "how"
   
   ### Documentation
   
   - [X] In case of new functionality, my PR adds documentation that describes how to use it.
     - All the public functions and the classes in the PR contain docstrings that explain what it does
     - If you implement backwards incompatible changes, please leave a note in the [Updating.md](https://github.com/apache/airflow/blob/master/UPDATING.md) so we can assign it to a appropriate release
