Globally disable follow redirects

[ArnyminerZ]

Purpose

We are trying to disable redirection following in the engine config. We don't even want to disable redirection, so remove that line.

We do have to disable redirection, it's handled by CalendarFetcher. Following the docs, this is the way to disable it so it can be handled by it.

Short description

• Remove the redirection disable in engine config.
• Move the redirection disabling
• Add a comment to make sure we don't get confused again in the future.

Checklist

• The PR has a proper title, description and label.
• I have self-reviewed the PR.
• I have added documentation to complex functions and functions that can be used by other modules.
• I have added reasonable tests or consciously decided to not add tests.

Where is the sense in leaving followRedirects = false ?
