fix: `EnqueueStrategy.All` erroring with links using unsupported protocols

[stefansundin]

This changes EnqueueStrategy.All to filter out non-http and non-https URLs (mailto: links were causing the crawler to error).

Let me know if there's a better fix or if you want me to change something.

Thanks!

@stefansundin do you plan to finish this? I'd rather not merge such change without any added tests

[stefansundin]

Hi @B4nan. I started writing a test but I had some more important work come up that took priority.

I may be able to finish it next week.

If you prefer then we can close this PR and open an issue instead.
