feat(@angular-devkit/build-angular): move milliseconds time audit at the end of console

In a project with a lot of lazy modules we need scroll console window to see Date - Hash - Time audit message.

This PR should keep Date - Hash - Time at the end on first `ng s` or `ng b` to see if first build just happend or not. On rebuild only Time is at the end which is most valuable

Before:
```
$ ng s
