Import failing from Jest since v5.0.0

[RubenVerborgh]

Since v5.0.0, we get:

    D:\a\community-server\community-server\node_modules\escape-string-regexp\index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){export default function escapeStringRegexp(string) {
                                                                                             ^^^^^^

    SyntaxError: Unexpected token 'export'

Looks like the move to ESM might not have been entirely successful.
