Affected Version:
Gerrit 2.11 with reviewers plugin from stable-2.11 branch

What steps will reproduce the problem?
1. Create a project with "/" in name, e.g. "aa/bb"
2. Try clicking on Reviewers tab in project screen
In the reverse proxy config "AllowEncodedSlashes On" is already configured.

What is the expected output? What do you see instead?
The reviewers plugin UI should be opened, but instead you get:

"Code Review - Error
The page you requested was not found, or you do not have permission to view 
this page."

Please provide any additional information below.

The generated link for Reviewers plugin web UI is:
https://<Gerrit Instance URL>/#/x/reviewers/aa%2Fbb
 instead of 
https://<Gerrit Instance URL>/#/x/reviewers/aa/Fbb 

This used to work correctly in Gerrit 2.10. It looks like this is a regression 
in Gerrit 2.11 in the way plugins contribute links in project context with 
project names including "/".

@Edwin, this regression was caused by this commit: [1]. Can you have a look?

It is correct that the project name is encoded in the URL
  https://<Gerrit Instance URL>/#/x/reviewers/aa%2Fbb

The Reviewers plugin should decode it.
