* Fix Route.ID() returns conflicting IDs

This commit fixes a bug where Route.ID() returns conflicting IDs.
For example, the configuration:

    receiver: test
    routes:
    - matchers:
        - foo=bar
      continue: true
      routes:
      - matchers:
        - bar=baz
    - matchers:
        - foo=bar
      continue: true
      routes:
      - matchers:
        - bar=baz

Gives the following Route IDs:

    {}
    {}/{foo="bar"}/0
    {}/{foo="bar"}/{bar="baz"}/0
    {}/{foo="bar"}/1
    {}/{foo="bar"}/{bar="baz"}/0

When it should give these Route IDs:

    {}
    {}/{foo="bar"}/0
    {}/{foo="bar"}/0/{bar="baz"}/0
    {}/{foo="bar"}/1
    {}/{foo="bar"}/1/{bar="baz"}/0
