EventTimeline: Fix baseIndex after removing the last event

Browse Source 
Removing the last event in an EventTimeline (as we might, for instance, if it
was a local echo in an empty timeline) got us into a state where the baseIndex
would increment when adding events to the end of the timeline, causing much
confusion.

// this is basically https://github.com/vector-im/vector-web/issues/937
// - removing the last event got baseIndex into such a state that
// further addEvent(ev, false) calls made the index increase.
