Memory leak detected for ConsoleViewImpl

[carymrobbins]

Reproducible by -

1. Run the ide task via gradle (ideally from IntelliJ).
2. From the newly spawned IntelliJ instance, open a Haskell project with a configured external tool (e.g. ghc-mod)
3. Confirm the Haskell Tools Console has output from an external tool
4. Close the project, then close the spawned IntelliJ.
5. Check the stack trace produced from the gradle process.

I've attempted to resolve this in the 417-mem-leak-ConsoleViewImpl branch by refactoring to use a ProjectComponent so that the console fields get disposed on project close, but that doesn't seem to have helped and the stack trace is still produced.
