Automatic tags from labels causes errors in prometheus integration

[akosveres]

Currently we're taking all the labels from the existing ApiCheck or Group resources, any automatic labels from other services will be automatically added as tags, this works as intended.

Checklyhq.com has a prometheus integration, this takes the tags on a check and makes it into a metric label.

At IMG Arena we had a restore procedure from a backup and this created additional labels on the ApiCheck resources, which created the tags on the checklyhq.com API Check as seen below:

The prometheus integration broke and we were unable to scrape the checklyhq prometheus endpoint as we received an error (do not have the error anymore unfortunately, will try to reproduce).

Removing the tags from the checklyhq.com api check fixed the problem.
