Describe the bug

We can create an unlimited number of filters using eth_newFilter. There should be a maximum cap on the number of filters that can be created, something like 100 or a bit fewer.

Each filter can potentially cause a performance hit in calls like eth_getFilterLogs, so we want to ensure that only a limited number can be created.

To reproduce

1. Go to api_run_tests and remove the call to ignore in the last create_eth_new_filter_limit_test test
2. Run forest-tool api test-stateful with similar parameters that are on the CI
3. See error

Expected behaviour

The test is passing, so we no longer need to call ignore on it.
