fix(build): TypeError: Class constructor BehaviorSubject cannot be invoked without 'new'

[FrancescoBorzi]

update by valorkin, thanks to ShinDarth:

• issue happens when tsconfig target is es6
• so workaround is to use es5 for now

It's a blocking issue to release v2

Fix: we should update build script to produce es5 and es2015(missing at the moment) version of ngx-bs

Bug description or feature request:

In my tsconfig.json when using "target": "es5" everything is fine, but if I use "target": "es6" I get the following console error every time there is an instance of the <timepicker>:
