Minor Python 2.7 fixes

Azure DNS dynamic record bug fixes

The test_login test from TestUltraProvider would fail in Python 2.7
due to the dictionary insertion order not being preserved in 2.7
and early 3.x versions. Comparing the dictionaries containing the
query parameters solves this. Snippet from test failure:

- username=user&password=rightpass&grant_type=password
+ grant_type=password&username=user&password=rightpass

Due to an import error the envvar source tests would not run
in Python 2.7

In Python 2.7 the if statement would catch both cases from the test
test_populate_lenient_fallback, so the test was failing. These are
the error strings differences between Python 2 and 3:

Python 2:
NoLenient: populate() got an unexpected keyword argument 'lenient'
NoZone: populate() got multiple values for keyword argument 'lenient'

Python 3:
NoLenient: populate() got an unexpected keyword argument 'lenient'
NoZone: populate() got multiple values for argument 'lenient'
