Set converse-profile as dependency of converse-omemo

Don't remove affiliation for occupants if we weren't allowed to
fetch that particular affiliation list.

Previously, if fetching the list failed, we would return an empty array,
which would imply that the affiliation list is empty and that all
users with the given affiliation should have their affiliations removed.

Instead we now return `null` and properly account for that when setting
affiliations on existing contacts based on the returned member lists.

We don't remove the existing chatboxes and upon refetching they
become stale and get removed (by Backbone) and then the UI for
them becomes unresponsive.

Don't remove cached presences in `afterTearDown` event.
We might reconnect again and resume the session, in which case we need
that data still.

Instead, we remove cached presences when `clearSession` fires, because
then we know we're not reconnecting.

When reconnecting, we don't fetch presences from cache, we still have
them (since we no longer remove them in `afterTearDown`).

When reconnecting and not resuming, we clear the presences from cache,
since we're starting a new session.

* Explicit forwards and backwards paging
* Include upper or lower bound when calling `RSM.prototype.next` or `RSM.prototype.previous`
* Bugfix: Don't override new RSM parameters (caused infinite recursion)

to conform to conventions

Also fix a bug in the code dermining whether an XMLElement stanza is only a chat state notification

* _.isNil
* _.noop
* _.isNull

We do that in `clearSession` and otherwise when we auto-reconnect we end
up without a roster.

to `show_chat_state_notifications`

Fixes #1548
