Getting rid of `unused parameter ‘lest_env’ [-Werror=unused-parameter]`

[medithe]

In the test-file lest_cpp03.hpp, the parameter lest_env may be not used in the expansion of the macro lest_CASE. This happens, when compiling with -Wunused-parameter.

The full warning:

Thanks @medithe, looks reasonable to me.

Note that env most often is used (review note).

However, please address this to the lest project itself. Afterwards, I'll update the file here

Wonder if the same holds for the C++11 lest.hpp.
