Resolve nested url can't change

[SergeShkurko]

Added default path ("/"). It resolve problem with subroute data change (#224 )

Before "Nested component" inactive, already - active

For example: url: 'localhost:8080/foo'

Before:

First component:
<app-location route="{{route}}"></app-location>
<app-route route="{{route}}" pattern="/:page" tail="{{subroute}}"></app-route>

Nested component:
<app-route route="{{subroute}}" pattern="/:subpage"></app-route>

// Route:
{
  prefix: '',
  path: '/foo'
}

// Tail
{
  prefix: '/foo',
  path: '' // default path == '' & subroute not active 😿
}

After

First component:
<app-location route="{{route}}"></app-location>
<app-route route="{{route}}" pattern="/:page" tail="{{subroute}}"></app-route>

Nested component (Added flag "auto-activate"):
<app-route auto-activate route="{{subroute}}" pattern="/:subpage"></app-route>

// Route:
{
  prefix: '',
  path: '/foo'
}

// Tail
{
  prefix: '/foo',
  path: '/' // default path == '/' & subroute active
}

Corporate signers

• Your company has a Point of Contact who decides which employees are authorized to participate. Ask your POC to be added to the group of authorized contributors. If you don't know who your Point of Contact is, direct the Google project maintainer to go/cla#troubleshoot (Public version).

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for all the commit author(s) or Co-authors. If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google. In order to pass this check, please resolve this problem and have the pull request author add another comment and the bot will run again. If the bot doesn't comment, it means it doesn't think anything has changed.

This is a simple solution to a common problem, but the issue is that this is a breaking change. would it be possible to put this behind a flag and also write a test for it?
