Subject: [PATCH] Fix version string for unsupported installations

For unsupported installations, $version['commit'] may not be defined,
leading to a warning:

E_WARNING (2)

Undefined array key "commit"
1. classes/config.php(316): ttrss_error_handler(Undefined array key "commit", classes/config.php)
2. prefs.php(173): get_version_html()
