Do not continue to autoreload the job page if a reload fails.

[phil-kremidas-unitedmasters]

Description

Autoreload causes the job page to hit the backend every couple of seconds. However, most RQ implementations set a TTL on jobs in redis. So, this polling will eventually fail. If it continues, it will do so continuously. This makes it difficult for users to set up monitoring and alerting, since these errors eventually overwhelm everything else coming from RQ dashboard. And, the refreshes are meaningless anyway.

This PR stops polling on the job page if a reload fails.

@cjlapao Do you mind taking a look at this? We use RQ dashboard quite a bit. And this issue occasionally comes up in our monitoring and requires just that little bit more effort for our oncall rotation.
