Fail canvas-media jest tests with console errors/warnings

An exception list is created for the existing errors and warnings
so that we can block new errors moving forward.

refs LF-534
flag = none

Test plan:
 - Without this commit, run `yarn jest` in packages/canvas-media
 - Expect to see a bunch of console errors/warnings
 - With this commit loaded, run `yarn jest` again
 - Expect to see no errors/ warnings
 - Add a new error to a test
 - Run `yarn jest` once more
 - Expect the test to fail
