If TESTS_TO_RUN contains a single parameter that cannot be expanded,
bash will not perform brace elimination. Remove braces manually.
For example, TESTS_TO_RUN='test_xmlrpc/test_*.py' will not expand
outside of ipatests and the script would generate
tests_to_run=-k{test_xmlrpc/test_*.py}
Braces then will prevent actual ipa-run-tests execution from matching
any of XMLRPC tests.
