Cpp: fix triggering of reactions in multiple nested reactors

[cmnrd]

The reactor-cpp runtime did not correctly handle multiple reactions in different nested reactors that are triggered by the same upstream port. This change pulls in a fix in reactor-cpp and adds an LF test.

@edwardalee, @Soroosh129 Do you know if we have a similar test for C?

I'm not sure, but I just added a C version of this test to the branch.

I couldn’t find a test that exactly matches what’s here (where you have two reactions at two different levels of the hierarchy be triggered by the same upstream port).

I did, however, find an apparent mistake in Hierarchy.lf, where in the main reactor we have:

container.out -> print.in;
container.out -> print2.in;

I think this should be:

container.out -> print.in;
container.out2 -> print2.in;

I just pushed a fix to this mistake to this branch.

Thanks for providing the C test! I will merge it then.
