Rewrite views to avoid locking and dependance to QWAT base export views

https://github.com/qwat/extension_sire/blob/master/extension/views/conduite.sql#L37

As a bad habit for simplicity purposes, we chose to buil SIRE export views on top of QWAT base views.

This is not good for long term maintenance of the solution. We have to rework this.
