Router.go doesn't take custom context into account.

[haijian-vaadin]

In a Spring Boot application, after setting a custom context root, e.g. in the application.properties file set
server.servlet.context-path=/context

Router.go('') takes the user to the context root, i.e. '/' instead of /context.

To reproduce:
Download a Vaadin Fusion app from https://start.vaadin.com/, set a custom context root as described above. Call Router.go(''), see that it directs the user to localhost:8080 instead of localhost:8080/context.

Keep in mind that this is nothing that can be determined on compile time, but instead can change on "deploy" - often this is changed with an external application.yml/properties depending on the provided server infrastructure, like e.g. / in development and /test or /prod for other environments.
