Update ScrollView units tests to not rely on cssreset

[derek]

The cssreset component was deprecated in v3.9.0, but a few ScrollView unit tests rely on that reset to normalize styles so various IE browsers reports consistent values for testing.

Ideally, these tests should not rely on additional components (that is more an integration test), but if it is necessary, explore using cssnormalize instead.

Also, if a reset is required for ScrollView, that should be documented and possibly be a dependency. Though, I see issues with forcing a reset on the page.
