'paused' event of .sync() does not emit errors from underlying replication

[maralorn]

Issue

When subscribing to

PouchDB.sync(…, { retry: true }).on('paused',myCallback)

the callback will always receive undefined. As opposed to

PouchDB.replicate(…, { retry: true }).on('paused',myCallback)

where the callback while receive undefined when there is nothing else to sync, but an error object when there is e.g. a connection problem.
