Current behavior
When displaying the pageReport the current page index is 0 based.

Expected behavior
My suggestion is to use 1 based indexing for the current page value.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?
I want to use the pagination report. This happens for independently defined paginator and included paginators aswell.

Please tell us about your environment:

• Angular version: 8.0.0-beta.12
