fix registerer nil deref from errors

[Freyert]

When the registerer is scanning processes and there are a lot of processes to check 429s are inevitable.

If we hit a 429 when registering we would log a debug level message and then continue to try and register the process.

Adding a break statement cause it to skip registering the rate limited process and continue with others.

We need to add an exponential back off with jitter RoundTripper to handle this better.

[Freyert]

Tomorrow:

1. Add a round tripper with exponential backoff and jitter
2. Swap the break for a continue statement
