Restore test for NEWUOA_BOUND

[aadler]

It seems to work on my PC.

I will check with a rocker image.

However, NEWUOA_BOUND is very very close to what BOBYQA does. In the spirit of your other PR #199, we might consider dropping it, and suggesting downstream packages who would use the dropped algorithms to use equivalent alternatives. Or even in nloptr.c select BOBYQA when user ask for NEWUOA_BOUND in the spirit of what I did for LBFGS_NOCEDAL.

WHOA!

test-nloptr.R................. 34 tests OK *** buffer overflow detected ***: terminated

I guess that's why we killed it. Let me dig into why.

Interestingly, it only has the buffer overrun in ubuntu release and not ubuntu devel. I don't know what that means.

In this case, we could skip the test for some specific versions of R. Although that does not solve the underlying root cause.
