Description of problem:
When comparing gnutls packages, abipkgdiff crashes when the command line
includes --redundant and --suppressions switch

Version-Release number of selected component (if applicable):
libabigail-1.0-0.8.rc6.4.fc24.x86_64

How reproducible:
Always

Steps to Reproduce:
1. abipkgdiff --redundant --suppressions
~/rhel-tests/gnutls/libabigail-suppressions --d1
gnutls-debuginfo-2.8.5-19.el6_7.x86_64.rpm --d2
gnutls-debuginfo-2.12.23-19.el6.x86_64.rpm gnutls-2.8.5-19.el6_7.x86_64.rpm
gnutls-2.12.23-19.el6.x86_64.rpm

Actual results:
abipkgdiff: abg-comparison.cc:8332: virtual void
abigail::comparison::fn_parm_diff::report(std::ostream&, const string&) const:
Assertion `get_type_diff() && get_type_diff()->to_be_reported()' failed.
Aborted (core dumped)

Expected results:
report printed
