Describe the bug
the -v flag should print the verbose output and all the trace information.
This is true when all of the tests are passing, but when one fails, the verbose output is suppressed.

To Reproduce
Steps to reproduce the behavior:

1. hcunit eval -v
2. on a failing tests
3. no verbose output will be printed

Expected behavior

1. hcunit eval -v
2. on a failing tests
3. verbose output will be printed (just as it is when all tests pass w/ -v flag)
