Improve test error messages from flutter

Browse source 
For some reason the error message from flutter SDK might contain no useful information. Basically it just says that test failed and you should see the logs. Logs itself are provided as content of `print` event. This commit adds special processing for this behavior - it parses actual error message out of print event.
