chore: remove/ignore tests which download from a remote server

[KolbyML]

What was wrong?

We had tests which would fail due to missing data on a website, some tests still fail too due to this, but we want those tests so I set them to ignore

How was it fixed?

removing the tests or ignore them. Trin Execution will still exit on start with the errors if any era files are missing so we are good

Yeah, sounds good. I'll close #1546

I do think we still want to have the error include which index is missing, like this commit: 531b0e1

Sounds good I made the error look like Epoch indices are not starting from zero or not consecutive: missing epochs [50, 500] as it looks nice
