[FIX] base, report: fix choose report template broken by 'new report'

Report module has been cleaned and moved into base at https://github.com/odoo/odoo/commit/e80238042c9d93d492ea8b06b0041aced0d81dcd.
However there are leftover references to report module. This crashes
the template choice feature.
