[Bug 907952] [NEW] Unnecessary log message when listing local services

[Walter Huf]

Public bug reported:

If the user connects to localhost:4949 and issues the "list" command
without passing a hostname, the following message showed up my logs:

Use of uninitialized value $1 in lc at
/usr/share/perl5/Munin/Node/Server.pm line 174, <STDIN> line 1.

To stop it, I changed line 174 in /usr/share/perl5/Munin/Node/Server.pm
as follows:

-        _list_services($session, lc($1));
+        _list_services($session, defined($1) ? lc($1) : undef);
