DRYing up the test suite using pytest fixtures (#2306) 

* add fixtures to conftest.py

* use fixtures in test_appctx.py

* use fixtures in test_blueprints.py

* use fixtures in test_depreciations.py

* use fixtures in test_regressions.py

* use fixtures in test_reqctx.py

* use fixtures in test_templating.py

* use fixtures in test_user_error_handler.py

* use fixtures in test_views.py

* use fixtures in test_basics.py

* use fixtures in test_helpers.py

* use fixtures in test_testing.py

* update conftest.py

* make docstrings  PEP-257 compliant

* cleanup

* switch dictonary format

* use pytest parameterization for test_json_as_unicode
