Testcases: remove "latest" if it is a symbolic link

Test for the existence of the symlink to "latest" with the -l flag,
which tests if the target is a symbolic link. Testing with the -e flag
will fail in case the link points to a file that does not exist, which
will occur if the test result directories are deleted by hand.
