I found a small bug in _get_namespace_and_simple_name.

Suppose I have a tree with two leafs: a function called a and a function called _a. Then, because of the rsplit method, the package things both functions have the same name, which results in an error in an input consistency check (we have the case in GETTSIM with lohnst_m and _lohnst_m). Essentially, the implicit assumption that, in the case of triple underscores in the qualified name, the module has a trailing underscore is wrong in my case.

Now, I guess the preferred solution is to get rid of the implicit assumption all together. To do this, we probably have to rewrite a few functions. I added a failing test such that we don't forget about this.

In the mean time, I reversed the implicit assumption via 811f211 such that it suits the application.
