[swift5] Fix request closure not being called

[fl034]

Fixes #8511

Self got deallocated due to [weak self] and no other strong references.
Because of that, request closures wouldn't be called anymore.

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh
  ./bin/utils/export_docs_generators.sh
  

  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master, 5.1.x, 6.0.x
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

@4brunu Podfile.lock of a test app is conflicting. Should I revert it? Or what's the procedure?

[4brunu]

I think you can delete it, and run pod install again.

[4brunu]

Looks good to me 👍

[4brunu]

Could you just run pod install on samples/client/test/swift5/default/TestClientApp/ to recreate the podfile.lock?

[fl034]

Done! Sorry, it was late yesterday :D @4brunu .
But what's the procedure now for the merge conflict?

[4brunu]

Sure, take your time 🙂
Could you fix the merge conflict with the master branch?

[fl034]

@4brunu I don#t get the conflict, since in the latest master commit the directory samples/client/test is not existing. Therefore the file can't be conflicting, right?

[4brunu]

Sorry for my confusion, you are right, the sample project in samples/client/test/swift5/default/TestClientApp was deleted.
Could you please delete the file?

@wing328 this PR is ready to merge, the CI is failing, but it's not related to this PR.
