Sylvain Munaut 4a9981ee77 pycontainers: Properly handle KeyErrors 
We raise a C++ exception to abort the rest of the execution of
the function.

At the same time we standardize on using a throw runtime error as the
method to avoid warning when not returning values. (some places
used this throw and some other used std::terminate)

Fixes #403
