Add regression-test for description-less repos

The segfault fixed in commit eacde43d7184452e1fdc90b982b531f1f5239923 was
triggered when the html-functions manipulated string literals. One callpatch
which could trigger the bug is in ui-repolist.c when repo descriptions are
passed to html_ntxt(): if a repo is lacking a description, the literal
string "[no description]" is used.

This patch changes test/setup.sh such that the first repo has no description,
and adds tests for both "[no description]" and "the bar repo" (description
of the other repo) to tests/t0101-index.sh, which should be enought to catch
regressions in these functions.

 # This file should be sourced by all test-scripts
 #
 # Main functions:
 #   prepare_tests(description) - setup for testing, i.e. create repos+config
 #   run_test(description, script) - run one test, i.e. eval script
 #
 # Helper functions
 #   cgit_query(querystring) - call cgit with the specified querystring
 #   cgit_url(url) - call cgit with the specified virtual url
 #
 # Example script:
 #
 # . setup.sh
 # prepare_tests "html validation"
 # run_test 'repo index' 'cgit_url "/" | tidy -e'
 # run_test 'repo summary' 'cgit_url "/foo" | tidy -e'
