Double-allocating resources does not raise an exception

It did in previous seasons. This makes it a bit too easy to not notice until you check the console, since the messages from WPILibC seem to not show when the DS mini-console is set to error level.

I tried customizing the trampolines, but realized after I was done that the trampolines are only used when python classes inherit the object. :(

I think this is something we won't be able to successfully do until 2021, because it would require hooking errorbase in the underlying library.

An alternative for teams that care (maybe we should do this in Magicbot?) is do the following at the end of robotInit:

errors = wpilib.ErrorBase.getGlobalErrors()
if errors:
   # print them...
   raise ValueError("OH NOSE")

This is fixed in 2022.
