[PATCH 0/1] MR8619: webservices/tests: Use valid url for WsEncodeUrl invalid argument tests.

[Jacek Caban (＠jacek)]

Fixes Clang -Wuninitialized-const-pointer warning.

We could also just have `memset()` initialization, but passing a fully valid URL makes it clear that URL is not the reason for `WsEncodeUrl` failures.
