[KleinanzeigenBridge] fix errors when <a> element is not found (#4820)

Sometimes a 'span' is present in place of 'a' in the content,
which would cause the bridge to fail.

- Use defaultLinkTo() facility instead of adding host domain name to
URL manually.

- Also use $this->getURI() in place of self::URI.
