404 error when requesting wasm

[rasmuslos]

This refers to https://github.com/ItalyPaleAle/prvt/pull/39

At the moment e2ee is not usable, because the wasm returns a 404 Error

As it turns out the problem was actually really simple to solve... The regex ^app(-([a-z0-9\\.-_]+))?.wasm$ does not match anything that contains - (for example v0.6.0-beta.1), so an easy fix would be to change it to ^app(-([a-z0-9\\.-_-]+))?.wasm$
