Remove: WordPress upload media mocks and alias.

[jorgefilipecosta]

The @wordpress/upload-media alias and mocks were added as a temporary solution because core was not properly bundling the package. But this issue was fixed upstream and meanwhile, the package versions we are using on calypso already contain the fix so these mocks are not needed.
