Add a dot in the placeholder IRC origin

Some clients may assume it is a nick otherwise.

> Servers SHOULD pick a name which contains a dot character (".", 0x2E).
> This can help clients disambiguate between server names and nicknames
> in a message source.

in actual nicks:

> They SHOULD NOT contain any dot character ('.', 0x2E).
