fix: Propagate Stream Errors through the same Future

[Gustl22]

Description

Wait simultaneously for async calls (Futures and Streams) to ensure all errors are propagated through one common future. Previously a stream could throw an error before it was even listened to, as the process still awaited an async call (here setSource).

Checklist

• The title of my PR starts with a Conventional Commit prefix (fix:, feat:, refactor:,
  docs:, chore:, test:, ci: etc).
• I have read the Contributor Guide and followed the process outlined for submitting PRs.
• I have updated/added tests for ALL new/updated/fixed functionality.
• I have updated/added relevant documentation and added dartdoc comments with ///, where necessary.
• I have updated/added relevant examples in example.

The tests are adapted, but not explicitly written to avoid that error. But the error would occur since Flutter 3.16.x, so they are tested against in #1715 without further ado.

Breaking Change

• Yes, this is a breaking change.
• No, this is not a breaking change.

@spydon we may can merge this even with the error (?). The problem seems to be solved with the linux workaround in #1715, but this requires pumping Flutter which is also happening there, and requires more changes. This "fix" should be logically independent from bumping, though. It's a chicken-egg-problem.

Let's just merge both? So that it still works for people depending on main

Yes, the lib works, even with the change, only the linux test fails, due to a the "pump" bug. But I would prefer to have two separate commits in the main branch, to have them separated in the log / changelog. After that, we can merge #1715

Thanks, unfortunately I cannot force merge with unresolved checks, maybe you have the permission to do so...

Nice 🥳
