BREAKING CHANGE:

* Remove component GlNavbar
* Remove prop 'isNav' from GlCollapse

Fix some timer related issues.

Now that @gitlab/ui and bootstrap-vue use the same versions of jest, we
simply can hoist the test execution up to @gitlab/ui.

Given that we are now testing on the top-level @gitlab/ui project, we
can get rid of these dependencies. Woop. Woop.

chore(bootstrap-vue): Use top-level jest jobs
