Correctly locate templates in a virtualenv (issue2550841)

The listTemplates() method looks in a number of locations under
'<venv>/local/' but the setup script installs them under the directory
'<venv>/share/roundup/templates/', so we need to add that to the list of
paths that are looked in for templates.
