Mateusz Loskot e22c7cb108 Fix GCC -Wsign-compare warning in tests (#217)
Fixes at least two warnings issued by channel tests due to
comparison of unsigned channel value with signed integer 1:

../../boost/test/tools/assertion.hpp:72:13:
  warning: comparison between signed and unsigned
    integer expressions [-Wsign-compare]
