Module checks for "/user" path rather than route name

Problem/Motivation

The module checks for hardcoded "/user" paths in lots of conditionals which means if the user route has been altered the module doesn't work as expected (for example, it checks whether it is on a '/user/register/{rid}' and '/user/{user}/edit' path to decide which form modes to check etc.).

Steps to reproduce

1. Install a module such as "Rename Admin Paths"
2. Change the user path to something like "account"
3. Install "Multiple registration module", whitelist a role, add a registration path and use a custom form display mode
4. Visit the registration path. This will lead to a 404 unless you manually change "user" in the url to "account"
5. Change the URL to "account" and visit your registration page, and it will not show the desired form mode

Proposed resolution

Where the module checks for "user" paths, use route checks instead.

None.

API changes
