 Description   

Running mapReduce with prepared transaction may cause deadlock due to SERVER-43242. Since mapReduce will be re-implemented as an aggregation pipeline, we need to remove the tests in 4.2. The deadlock will resolves after the prepared transaction times out after one minute by default.
