Add DQMH Validation test: "DQMH_HELPER_LOOP_NAME" string constant wired to the error helper VI.

[ChrisFarmerWIS]

For DQMH modules written prior to DQMH 7, helper loops will unlikely have the "DQMH_HELPER_LOOP_NAME" string constant wired to the error helper VI as shown below.

This idea is to propose a new test be added to DQMH Validate Module to check that all helper loops have this string constant present.
