Fix aws unit tests

[xquek]

Hi @henriqueribeiro and @geertvandeweyer,

Thanks for maintaining the fork. This Pull request is to update the following tests to account for recent updates: These are changes to get the tests to compile. I also removed some trailing white spaces in AwsBatchJob.scala please do take a look and let me know if there is any issue! thanks

Replacing mockito-sugar with vanilla mockito

It looks like mockito-sugar was removed as a test dependencies. Use vanilla mockito instead.

• AmazonEcrPublicSpec.scala
• AmazonEcrSpec.scala

Missing imports

I think this might be because the package renamed from cromwell.backend.impl.aws to cromwell.backend.impl.aws.io for AwsBatchJobPaths, AwsBatchWorkflowPaths,AwsBatchWorkingDisk`

• AwsBatchAsyncBackendJobExecutionActorSpec.scala
• AwsBatchAsyncBackendJobExecutionActorSpec.scala
• AwsBatchCallPathsSpec.scala
• AwsBatchWorkflowPathsSpec.scala

Missing Args and imports

With the introduction of new EFS feature, there are some missing args AwsBatchJob and AwsBatchRuntimeAttributes

• AwsBatchRuntimeAttributesSpec.scala
• AwsBatchJobSpec.scala
