chore(package): update jasmine to version 3.0.0 (#4553)

* chore(package): update jasmine to version 3.0.0

Closes #4547

* Fixes failing tests for jasmine 3.0

Starting 3.0, done(something) will fail

* Update tests so they dont leverage var, but let and const

With jasmine 3.0, the randomization engine was making the test fails because of the scope of `var`

* Remove randomizer

* Use same adapter for PG tests, drop table to ensure the tests dont side effect
