Report the first rule error as a root cause event

This is not fool-proof. In particular, it is missing all errors
generated in the ConfiguredTargetFunction. However, it should give
us significantly better coverage being a more generic mechanism.

We might want to consider either adding an index to the root cause
events so we can report multiple, or collecting all error messages into
a single root cause event for each target.
