chore(*): Upgrade to Jasmine 2.4

Highlights:
New mechanism to run async tests as Jasmine 2 removed `runs`, `waits` and `waitsFor`
The functions `iit`, `ddescribe` and `tthey` were renamed `fit`, `fdescribe` and
`fthey` as the originals came from Karma, Karma no longer bundles Jasmine and the
new function name comes from Jasmine.

Closes #14226
