lsp-show-workspace-symbol doesn't work on omnisharp-roslyn if lsp uses plists instead of hashmap

[Arnob90]

Thank you for the bug report

• I am using the latest version of lsp-mode related packages.
• I checked FAQ and Troubleshooting sections
• You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

If LSP_USE_PLISTS is set to true, then when trying to use helm-lsp-workspace-symbol, I get the following error.

However, if lsp doesn't use plists, then it works as intended.

Steps to reproduce

Just use (setenv "LSP_USE_PLISTS" "true"), build lsp-mode, and run a csharp file with omnisharp.

Expected behavior

It should show a list of all symbols defined in the code.
