[Uptime] ML job creation fails on some monitor names

[andrewvc]

I tried to enable ML on a monitor with an autogenerated ID and got the following error:

Looking in the network debugger I see the following response:

We should:

1. Surface the error visibly to the user
2. Only send valid job names. I'm a bit confused because the job name seems valid. We need to see what's up here.
