Before this commit, the test assets were called with a `t-call-assets` and contained themselves some other `t-call-assets` to the back-end assets. According to the current specification, having nested `t-call-assets` will result in a compilation of the lower levels regardless of the current debugging mode. Now, the test bundles (desktop & mobile) have been arranged so that their `t-call-assets` are all called on the same level. closes odoo/odoo#49306 Related: odoo/enterprise#9797 Signed-off-by: Aaron Bohy (aab) <aab@odoo.com>
