IDE may be loading Std library twice

[markrtuttle]

The IDE complains "Duplicate module name: FileIOParser" if I load a project containing the following two files that use the new Std standard libraries. Reproduce this error using the attached tar file example.tar.gz.

test.dfy

module Test {
  import opened Std.Wrappers
  function count(i: int): Option<int> {
    if i < 0 then None else Some(i+1)
  }
}

dfyconfig.toml

[options]
standard-libraries = true

Run code . in the enclosing directory using a recent dafny nightly (nightly-2023-12-10-4faa561) and open the file test.dfy. The extension will resolve and verify the file as expected. Type a space anywhere in the file. The extension will start resolution and report "Resolution Failed" and point to the first like of the dfyconfig.toml file. The error message will be

Files referenced by project are:
test.dfy
DafnyStandardLibraries-notarget.dfy
DafnyStandardLibraries-notarget.dfy
DafnyStandardLibraries.dfyParser

the referenced file DafnyStandardLibraries-notarget.dfy contains error(s) but is not owned by this project. The first error is:
Duplicate module name: FileIOParser

Run "Restart Dafny" and the file will verify successfully as before. Repeat...

Similar to Dafny issue dafny-lang/dafny#4858 and possibly fixed by pull request dafny-lang/dafny#4861 fixing the language server.
