Rectify TypedCounter_test fixture -- Type-IDs are not stable

Browse source 
Hehe...
with GenNode, we started to use these global Type-IDs to generate
unique Names for unnamed Children in a diff::Record. This means,
when running in the test-suite, the TypeID for 'short' and 'long' are
likely to be allready allocated, so our Test can not not observe the
allocateion, nor is it sensible to assume fixed numbers for these Type-IDs.
Instead, we create two local types right within the test function, to force
generation of new unique type-IDs, which we can observe
