fix(@angular/cli): fix test typings

Blocked by angular#5500

Our unit test webpack config was erroneously sending in entry points to karma-webpack, who should receive no entry points.

This in turn was hiding errors related to typeRoots lookups.

It was also causing unit tests compilation to behave weirdly: unit test errors would not stop compilation, because other entries would still compile.

This might also have contributed to the overall slowness of unit tests in angular#5423.
