Existing Cloudflare Workers Routes not detected?

[pro-sumer]

Describe the bug
Existing Cloudflare Worker Routes are not detected by DNSControl (happens both with routes added manually on the Cloudflare dashboard and routes added by DNSControl itself).

Results:

1. "preview" always lists all (existing) worker routes defined by DNSControl as corrections
2. "push" will try to push these "corrections", but fail with FAILURE! workers.api.error.duplicate_route (10020)

To Reproduce

1. Create a Cloudflare Worker Route (either manually or using DNSControl)
2. Put the same route in a CF_WORKER_ROUTE entry in your dnsconfig.js config file
3. dnscontrol preview ...
4. dnscontrol push...

Expected behavior

• Existing worker routes are detected.
• Only real changes are reported as corrections.
• (Only) Those corrections can be pushed successfully.

DNS Provider

• Cloudflare

Out of curiosity I tried an old build with "diff1" instead of "diff2", but the issue is still present with that older diff/build.
