Private methods in a module, and modules in BangleApps

Ahh - so yeah, what's happened is the core submodule is out of date somehow.

core/js/appinfo.js should looks like https://github.com/espruino/EspruinoAppLoaderCore/blob/8bfdeebf705ced95699dcbbccfa05a99e7d3f4a9/js/appinfo.js:

// Run JS through EspruinoTools to pull in modules/etc
function parseJS(storageFile, options) {
  if (storageFile.url && storageFile.url.endsWith(".js") && !storageFile.url.endsWith(".min.js")) {
    // if original file ends in '.js'...
    var localModulesURL = window.location.origin + window.location.pathname.replace(/[^\/]*$/,"") + "modules";
    return Espruino.transform(storageFile.content, {
      SET_TIME_ON_WRITE : false,
      PRETOKENISE : options.settings.pretokenise,
      MODULE_URL : localModulesURL+"|https://www.espruino.com/modules",
      //MINIFICATION_LEVEL : "ESPRIMA", // disable due to https://github.com/espruino/BangleApps/pull/355#issuecomment-620124162
      builtinModules : "Flash,Storage,heatshrink,tensorflow,locale,notify"
    }).then(content => {

But on yours it looks like:

function parseJS(storageFile, options) {
  if (storageFile.url && storageFile.url.endsWith(".js") && !storageFile.url.endsWith(".min.js")) { // if original file ends in '.js'...
    return Espruino.transform(storageFile.content, {
      SET_TIME_ON_WRITE : false,
      PRETOKENISE : options.settings.pretokenise,
      //MINIFICATION_LEVEL : "ESPRIMA", // disable due to https://github.com/espruino/BangleApps/pull/355#issuecomment-620124162
      builtinModules : "Flash,Storage,heatshrink,tensorflow,locale,notify"
    }).then(content => {
