Fix an assert in purple_markup_html_to_xhtml

While `g_string_free` is NULL-safe, the assert for passing it in breaks
ossfuzz. This can happen if there is no `src=` in the `img` as expected.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35029

Testing Done:
Ran the test case from the bug against `fuzz_html_to_xhtml`

cat <<EOF
This program calls purple API functions using DBus. As opposed to purple-send,
it does not print the return value.
Usage:
$0 method-name type1:parameter1 type2:parameter2 ...
This shell script just invokes dbus-send, see man dbus-send for how
to specify the parameters.
Examples:
$0 PurpleCoreQuit
Use dbus-viewer to get the list of supported functions and their parameters.
