module-gsettings should ignore module-esound-protocol-tcp if esound is disabled
When enabling remote access with paprefs, module-esound-protocol-tcp is added to the list of modules that module-gsettings loads. If esound is disabled, that will cause an error message to be logged: "Failed to open module module-esound-protocol-tcp.so: module-esound-protocol-tcp.so: cannot open shared object file: No such file or directory"
