oeqa/utils/decorators: Try and improve ugly _ErrorHandler tracebacks
Currently, if one module is skipped, any other module calling skipModule
causes tracebacks about _ErrorHandler not having a _testMethodName
method.
This reworks the code in a way to avoid some of the problems by using
the id() method of the objects. It also maps to the correct name
format rather than "setupModule" or just skiping the item entirely.
