Fix test_none_collisions on 32-bit systems (#69)
There are two issues at play here:
1. Python version of `map_hash` unnecessarily performs hash truncation
even if the hash is already 32-bit wide, which potentially converts
it from signed int to unsigned long.
2. The `test_none_collisions` test generates a collision node with
hash greater than 2^32.
Both of these are problematic on 32-bit systems, where `sizeof(Py_hash_t)`
is 4, and so anything that doesn't fit into `Py_hash_t` gets bit-mangled,
breaking the `hash(x) != x` invariance that the test relies upon.
Fixes: #53
Fixes: #50
