[PATCH 2/6] Fixed a memory leak in webservice.c

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

webservice.c:webservice_download_dialog()
If a value for previous UID is returned from the user config
via subsurface_get_conf("webservice_uid"), make sure to
free the string near the function return.
