   ## What is the purpose of the change
   
   As described in the related jira, this PR targets the in-progress files left after a failure, that belong to no checkpoint. In this case, we lazily overwrite them as soon as the new tasks arrive to that part-counter.
   
   ## Brief change log
   
   Just removes the random suffix from the `LocalRecoverableWriter` and the `HadoopRecoverableWriter` so that the temporary files are overwritten.
   
   ## Verifying this change
   
   Added 2 tests in the `AbstractRecoverableWriterTest`.
