A problem not to detect amended commit in the RepositorySensor #6
Description
The sensor to monitor the Bitbucket repositories is implemented in #5.
But that implementation has a problem in the processing of detecting an update on a repository. That can't detect an amended commit.
Sensor determines 'update' by comparing a newer commit than the last detected one with the commit-time.
But an amended commit can't be notified, because that will be same time with the replaced one.
