[OE-core] [PATCHv2 1/2] oeqa/core/loader.py: Give meaningful error when failed to load classes

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

With this we get the class that is actually having the problem,
not just a TypeError with an unknown class causing the error.
