[fix] metadata issue, fixes #74

[lucagouty]

Summary of changes:

• Change imports to fix metadata issue

Honestly, I'm not sure what was the issue, but I found that fix in ngx-progressbar which had the same issue some time ago :

• Issue : ERROR in Error during template compile of 'CoreModule' Function calls are not supported in decorators but 'NgProgressModule' was called. MurhafSousli/ngx-progressbar#160
• PR : https://github.com/MurhafSousli/ngx-progressbar/pull/168/files

Other unrelated changes (I'll rollback if you want)

• Update npm-run-all (I would keep that one, see I don't know what to say. dominictarr/event-stream#116 ⚠️)
  Also, I couldn't make npm i to work without it, because npm ERR! 404 Not Found: flatmap-stream@0.1.1
• Add baseUrl to tsconfig (required for "paths")
  

Intended/example use case:

Of course, first I made sure I was reproducing the issue, without this change, I get

ERROR in Error during template compile of 'CoreModule'
  Function calls are not supported in decorators but 'IntercomModule' was called.
: Unexpected value 'undefined' imported by the module 'CoreModule in /some/path/src/app/core/core.module.ts'
Error during template compile of 'CoreModule'
  Function calls are not supported in decorators but 'IntercomModule' was called.

With this fix, everything goes well now (Angular7, both ng build --prod and ng xi18n)

Checklist:

• npm run build runs without error
• ng serve spawns app, Intercom messenger is visible and interactive, and there are no errors in the console

Closes issue: #74

I think this should be enough, but I don't want to take a risk, so let me know if you want me to update it :

export { Intercom } from './src/app/ng-intercom/intercom/intercom'
export { IntercomConfig } from './src/app/ng-intercom/shared/intercom-config'
// export { IntercomHideDirective } from './src/app/ng-intercom/directives/hide.directive'
export { IntercomModule } from './src/app/ng-intercom/intercom.module'
// export { IntercomShowDirective } from './src/app/ng-intercom/directives/show.directive'
// export { IntercomShowMessagesDirective } from './src/app/ng-intercom/directives/show-messages.directive'
// export { IntercomShowNewMessageDirective } from './src/app/ng-intercom/directives/show-new-message.directive'
// export { IntercomShutdownDirective } from './src/app/ng-intercom/directives/shutdown.directive'
// export { IntercomTrackEventDirective } from './src/app/ng-intercom/directives/track-event.directive'

npm run test and ng serve both work with only those 3 exports (as does our app)

Thank you for the PR! I'm going to close and reopen this to trigger the CI.
