If jinja template initialization, parsing, rendering, or writing fails, we used to sometimes log an error message, then sometimes continue (ignoring the failure), sometimes reraise the exception, and sometimes fail without raising the exception. With this change, we always raise the exception so we print the traceback and fail the build right away. Change-Id: I04a36c4c8c69dbd08e9ea677983dbe00fa3a67a3
