CLI -t trace option doesn't work for daffodil test commands in TDML

This command does not cause tracing:

daffodil -t test -iii src/test/resources/owl/myTests.tdml testName

It is important and very convenient when using CLI and TDML to be able to trace a single test. 

The general -t (for trace) option should apply to running TDML as well as parse/unparse.
