ui: Upgrades ember and related to latest 3.20 LTS release (#8761)

* ui: Upgrades ember and related to latest 3.20 LTS release

* Delete ember-portal related tests

As we are running inline and block component tests in the same test an
error is raised as we are adding the same named portal twice.

Tests were deleted here as they weren't really testing anything anyway
