Remove %YDBAIMTEST trap unwinder; reenable tests
The YDBAIM code finally has an error trap that unwinds properly from deep levels of its stack. As a result, the unwinder in the error trap is no longer needed and is now removed. This in itself will be a good test of the error trap unwinding properly.
In addition bash tests INVPNUMSEP and CANTADDSTAT are now reenabled.
