Flow fails to push with a flowDefinition the first time

[pcon]

If you try to push a new flow file to an instance without a single version and you include a flowDefinition the flow will fail to push with the following error

flowDefinitions/NEP_Notification.flowDefinition -- Error: You can't create a flow definition directly through the API. A flow definition is created automatically when you create a new flow version.

The temporary workaround is to add flowDefinitions/* to the sfdcignore file and push the flow. Then active the flow by removing it from the ignore file with the next push.
