Fix channel names for terms with multiple `::` separators

[granitibrahimi]

Actually on Workspace when the channel name is built there is a replace which replaces first occurrence of :: with a .. Pusher does not allow names with :: so method replace is adjusted to replaceAll so it replace all occurrences.

Example channel name generated from terms: presence-term.ad::test-slug::default.default
