added unescape for email text body to avoid encoded characters

[Jin-Sun-tts]

The harvest report emails sent to users contains encoded characters, like ' and "

This makes it hard for users to understand the error message. For example:

before
ERROR #1: 'description':'' is too short.

after
ERROR #1: 'description':'' is too short.

cc @amercader @avdata99 , this is due to data.gov email formatting problems.

@jbrown-xentity , I think it's good for Python 3 but we need to cover Python 2 users (CKAN <= 2.9-py2) users
html.unescape is only available from Python 3.4
Tests for this extension still check from CKAN 2.7

Check your GitHub actions:

Thanks @avdata99 , we'll push something with six handling the Py2 use case...
Any reason why the checks don't show up on the PR? When we push more commits, is there a way for us to know the results of the tests without asking you?

@jbrown-xentity, this repository takes care of the minutes to execute the GitHub actions. This is why it requires the authorization of a repository administrator user to run.
Forks of this repository do execute these actions (including tests) and each external user can check their own tests.

LGTM
