Make nixd's noogle.dev code action workaround also work in case of invalid syntax

[Meallia]

Follow up to #100

The nixd noogle.dev workaround did not work in case of syntax errors in the nix file, in that case, the LSP client would also try to create a quickfix, resolve the original code action and open a new browser tab.

Applying the workaround in both createQuickFix and createIntentionAction made the "Open Noogle documentation" option appear twice. I tried disabling it in createQuickFix but it would also disable it in createIntentionAction, so I choose to discard it instead.

Tested with this (invalid) nix file

lib.getExe;
