Update angular and tsickle dependencies

[alan-agius4]

feat(@schematics/angular): use angular version 7.1.0

feat(@schematics/angular): use tsickle >=0.34.0 when creating a library

build: update @angular/packages to 7.1.0

I got an error like

"Uncaught TypeError: You provided 'undefined' where a stream was expected. You can provide an Observable, Promise, Array, or Iterable."

after changing tsickle from >=0.25.5 to >=0.34.3

It is really strange.

"@angular/core": "^7.2.8"
"@angular/cli": "^7.3.5"
"typescript": "~3.2.4"
"rxjs": "^6.3.3"

As soon as I roll back tsickle, everything works as usual. I haven't figured out what happened exactly.

update

if I set it to 0.34.0, it works. But when I tried 0.34.2, it throws errors again.

I forgot to mention it only happens under production build.
