Fix Desktop Build on Linux (#954)

WebAssembly needs a specific mime type to be allowed to be loaded. Tauri
by default apparently can't send headers on Linux, unless you activate a
specific feature, so the WebAssembly failed to load. Additionally,
without the dialog feature, it also wasn't able to show the error
message.
