Two new errors in share_testsuite



Revision 1.72 of defint.lisp causes two new errors in the
share_testsuite:

Running tests in rtest_simplify_sum:

********************** Problem 52 ***************
Input:
test_sum(sum(harmonic_number(n)/n/(1+n),n,1,inf),[],false,[],%pi^2/6)


Result:
(3*('limit(2*li[2](%e^?g1467538)+2*?g1467538*log(1-%
e^?g1467538)-?g1467538^2,
           ?g1467538,inf))
 -2*%pi^2)
 /6

This differed from the expected result:
0

********************** Problem 54 ***************
Input:
ev(test_sum(sum(harmonic_number(n)/n/2^n,n,1,inf),[],false,[],%pi^2/12),
   sum_by_integral_transforms = [logcontract])


Result:
(4*log(-1)*log(2)+4*li[2](2)-%pi^2)/4

This differed from the expected result:
0
