Fix tests and Linux support

## Changes

- Fix unit tests.

- Remove unnecessary Combine imports

- Fix imports on Linux.

- Fix unit tests on Linux
  + Add missing compile checks for `XCTExpectFailure` in Linux
  + Disable tests that use `@MainActor` on Linux because of an issue
  gathering tests:
  https://github.com/apple/swift-corelibs-xctest/issues/424

- Remove Swift installation from SwiftPM Linux job, as Swift is already
included in `ubuntu-latest` (`ubuntu-20.04`):
https://github.com/actions/runner-images/blob/main/images/linux/Ubuntu2004-Readme.md#language-and-runtime
