Purging from Nomad UI does not work because parameters are passed incorrectly

[Kamilcuk]

Nomad version

Nomad v1.6.2

Operating system and Environment details

Fedora 29

Issue

Nomad UI sends wrong request when purging.

Reproduction steps

Create a job not in default namespace. Stop it. Click to purge it.

Expected Result

Should be purged.

Actual Result

Not purged.
When clicking "purge job" from the ui I see in chrome network debug view that it sends the following query:

 <url>/v1/job/jobname?namespace=dev?purge=true

It's wrong, it should be namespace=dev&purge=true.

I completely guess, I know nothing about javascript, this is caused by adding ?purge here:

https://github.com/hashicorp/nomad/blob/main/ui/app/adapters/job.js#L47

Where the ?namespace is added here:

https://github.com/hashicorp/nomad/blob/main/ui/app/adapters/watchable-namespace-ids.js#L54

Hi @Kamilcuk , good find — seems we're not handling query params the right way here. Will look into a fix.
