init.sh: don't let bash aliases interfere with tests

* tests/init.sh: Undefine any pre-defined aliases if the selected shell
is bash.  This avoids problems for those who alias standard commands to
non-conforming uses, like those reported in http://bugs.gnu.org/11256.
Suggested by Tim Mooney <Tim.Mooney@ndsu.edu>.
