Preview job resuming with an other account.

**Describe the bug**
Hello,
Using the preview function when we post a job is resuming with a different account and with the same device (laptop).
More details:
When we are connected as for exemple " Alpha1" we click on post a job, we fill up all the necessary thing then We click on preview. a this moment if we disconnect and connect with an another account " Alpha2" And we click on post a job, There is a mention saying " You are editing an existing job" and job itself its the job i'v not finished with alpha1.
That curious.

We are using:
Lastets versions of WPJOBManager and addons.
Latest version of Wordpress
Latest version of Buddypresstheme and buddypressPlatforme.

Reproduce the preview flow by starting a job as Alpha1, disconnecting, and starting another as Alpha2 on the same laptop. Trace how the unfinished job is retained between preview and the next posting session; done means Alpha2 does not see or resume Alpha1's draft.
