Before this commit, processing of pinned channels during init_messaging was slow due to sorting them in sidebar of discuss.

Before what took 2.2 seconds now takes around 0.6 seconds. closes odoo/odoo#108839 X-original-commit: dd4c3c0a8e38147065980cf2c431b056a5253255 Signed-off-by: Alexandre Kühn (aku) <aku@odoo.com>
