odoo/odoo#136944 removed the log from website_event_track, but despite noting the discontinuity I missed that *a new instance of the log line had been added in 16.1* and that is likely why 16.1 was suddently spammed with that: website_event_track (likely) only installs its PWA when opening an event on website, but since odoo/enterprise#35322 the web client tries to install its PWA *every time it's loaded*, which can be up to once per test for qunit tests (if they need a webclient). In odoo/odoo#133560 this registration was moved from enterprise to community, so needs to be nuked here as well. Follows the removal of this log line in odoo/enterprise#48831. closes odoo/odoo#138469 Signed-off-by: Xavier Morel (xmo) <xmo@odoo.com>
