Fix a bug for multi-writes in ResourceUsageTrackingTests.cpp

It is valid to have race condition for multiple writes on the same
resource in some situations in render pass. These situations are:
1) multple storage buffer bindings on the same buffer,
2) multiple writeonly storage texture bindings on the same texture.

This change fixed a bug in tests and added a new test, in order to
make sure that validation code in Dawn allows this kind race condition.

Bug: dawn:407
