Remove unnessary usage of Tab.getNativePtr().

Remove unnessary usage of Tab.getNativePtr().

We shouldn't be asking for native pointers from java. All that was
needed was a WebContents, so use that directly.

getNativePtr isn't called anymore but can't be removed until the downstream
override is gone which needs this patch to roll down.
