Motivation
fix #2497
The reason for the problem is that runnable's execution is asynchronous, and
com.facebook.datasource.AbstractDataSource#mDataSourceStatusmay change during this time.Because the first execution to this line will eventually result in the mDataSource being null, even though the two fields are the same on the second execution (line 5 of the log), the method returns false because the mDataSource is null, resulting in the onFailure method not being called(this method will return false).
