    tests: Fix invalid call to tracker_getline in libtracker-extract test
    
    The test passes when used with glibc's getline(), but the fallback
    implementation we ship will return EINVAL if the size pointer is not set
    to zero before the call. The man page suggests that this is valid
    behaviour for a getline() implementation, so let's fix the test.
