Nomad UI - Cannot access allocation until allocation status changed

### Nomad version
Nomad v0.11.3 (8918fc804a0c6758b6e3e9960e4eb2e605e38552)

### Operating system and Environment details

Ubuntu 18.04

### Issue
This had started with 0.11.x upgrade. When job is about to run (allocations are in pending state) I cannot click and view allocation for the first 5–10–15 sec. It may even fail and restart during this time but still its not accessible right away.

### Reproduction steps
Run any job.

### Job file (if appropriate)
I observer this behaviour with all jobs.

### Nomad Server logs (if appropriate)
```

May it hang until vault issues new tokens? Most of my jobs have some secrets, so I'm using template stanza's.

No files, tests, or entry points are identified. Start by running any job and checking whether its allocation is inaccessible while pending, including jobs using the template stanza and Vault secrets; done means the allocation is viewable immediately and remains accessible through failures or restarts.
