[FIX] web: tests: detect failed modules in small suites

Before this commit, we waited for 10 seconds before defining the
boot test (checking that all JS modules have been correctly
loaded). However, small test suites (like the mobile one) ended
before this test was defined. So we could end up with a green
branch with tests not being executed (e.g. if a testing module
had missing dependencies, and was part of a small suite).

This commit removes the boot tests and instead does the check
at the end of the suite, before logging that the suite passed.

closes odoo/odoo#50109
