message: fix(core): don't ship an Ivy compiled library
  Shipping as Ivy compiled is not recommended by Angular it it breaks
  every library that has a dependency on ngx-bootstrap and that does
  not ship as Ivy  compiled.
  Enabling "fullTemplateTypeCheck" also works around an Angular compiler
  problem regarding the `forRoot()` not working..
