QmlProfiler: Limit hard resetting of QML debug connection

Browse Source 
On windows it can take a long time to establish the connection. On OSX
we want to throw away the first connection after trying for 200ms. We
don't want to introduce #ifdefs here, so after throwing away two
connections stick to the third one.
