<rdar://problem/8441042>

A reproducible case is typing "doesn'". After typing the apostrophe, the string is corrected into "doesn'does'". This exposes in fact two bugs.

1. After typing "doesn", the correction panel timer is started. If the apostrophe is typed before the time fires, by the time the timer fires, we end up checking spelling on "doesn'" instead of "doesn". The solution is to stop timer whenever the selection changes.

2. If the spelling checking is done for the purpose of bringing up correction bubble, we should suppress any suggestion correction whose range does not end at the last character. In this case, the correction range ends at letter "n" which is the second to the last.This is generally a good policy since it is confusing if we alter other text at the same time we show the correction bubble.
