fix(client): route param regex overflows container

[adamdehaven]

Truncate the path to account for custom regex in the route params. Fixes #235.

To illustrate, you can define a route with custom regex in the param as seen here for a UUID:

{
  path: '/hello/:id([0-9a-fA-F]{8}\\-[0-9a-fA-F]{4}\\-[0-9a-fA-F]{4}\\-[0-9a-fA-F]{4}\\-[0-9a-fA-F]{12})',
  component: () => import('./pages/Hello.vue'),
  name: 'hello',
}
