Noise in unit test output (stderr messages)

[Stuart McLaren]

Output such as the following is being printed to stderr on each test run:

$ ./run_tests.sh

    Hide stderr noise in test output

    Previously, some tests caused the usage options for glance to be printed out to
    stderr. This patch redirects the stderr output for those unnecessarily verbose
    test functions.
