Bug: Blazor route discovery cannot discriminate subroutes after a parameter

[conficient]

A set of routes with different subroutes after a parameter overwrite previous routes causing mismatch.

In the BlazorRouteTests amend the code for MatchesTemplateWithParameters as follows:

 [Fact]
 public void MatchesTemplateWithParameters()
 {
 string[] templates =
 {
 "/Cats/{id}/Breed",
 "/Cats/{id}",
 "/Cats/{id}/Owner",
 };
 var target = new BlazorRoutes(templates);
 Assert.True(target.Contains("cats/42"));
 Assert.True(target.Contains("cats/42/owner"));
 Assert.True(target.Contains("cats/42/breed"));
 }

The first two tests pass but the second fails, because the last parameter route (owner) overwrites the prior one.

Seems to be a logic error in RoutePart.cs when adding routes..
