Remove duplicate 'Reference' active pattern

[Numpsy]

Not sure what the history is here, but when I try to do a local build I get

  FsAutoComplete.Core net8.0 failed with 1 error(s) (3.0s)
    G:\Dev\FsAutoComplete\src\FsAutoComplete.Core\CompilerServiceInterface.fs(229,8): error FS1182: The value '(|Reference|_|)' is unused

but there appears to be two copies of the same function - this one and one on line 199 - which looks wrong anyway?

Maybe down to dotnet/fsharp#19805 in the compiler. causing the 10.0.400 version to pick this up where the older ones didn't

Same with this other CI error I suppose

/home/runner/work/FsAutoComplete/FsAutoComplete/src/FsAutoComplete/LspServers/FSharpLspClient.fs(196,7): error FS1182: The value 'strEquals' is unused [/home/runner/work/FsAutoComplete/FsAutoComplete/src/FsAutoComplete/FsAutoComplete.fsproj::TargetFramework=net10.0]

[Numpsy]

I guess the .NET 8 failures are down to the issues from #1537?
