Add guards to avoid calling strchr when @err_noinfo == NULL or
calling virErrorTestMsgFormatInfoOne when @err_info == NULL as
both would fail with a NULL deref.

Make sure that we don't add any broken error message strings any more.

This ensures that both the version with and without additional info is
populated, the version without info does not have any formatting
modifiers and the version with info has exactly one.
