[FIX] web: increase timeout for js tests
[FIX] web: increase timeout for js tests

We have a new runbot server which is quite slow.  Because of this, it
takes too much time to run this unit test suite (for comparison, one of
the last build by the main runbot takes 126s).

This is necessary for now, until we use chrome headless or something...
