NgModule fix

When building app in release mode, it was complaining about missing NgModule() in file bottombar.module.d.ts. By adding it, everything seems ok.

@marayfirth thanks for the PR

Build failing because of wrong path of the ios demo build folder will need to fix that and make sure it works in any circumstances.

Will make sure that this can't be generated from tsc command.

Otherwise will merge this PR
