Devfile could not be found in the branch which name contains '/' sign

[svor]

Describe the bug

In some cases users could have devfile.yaml file in the branch that contains / sign.
The problem is that it is not possible to create a workspace via factory by using this devfile.yaml.

In the dashboard I see a message like: "Devfile could not be found in repo. Applying the default configuration"

Che version

next (development version)

Steps to reproduce

1. Create a branch with / sign in your repository with devfile.yaml
2. Try to create a workspace by factory using this branch

OR

try this factory: https://che-host/#/https://github.com/svor/quarkus-api-example/tree/new/branch
in the dogfooding instance it's https://che-dogfooding.apps.che-dev.x6e0.p1.openshiftapps.com/#/https://github.com/svor/quarkus-api-example/tree/new/branch

Expected behavior

The workspace should be started from the existing devfile

There are a couple of workarounds for this issue. Although they are not ideal and we need to address this issue, I am adding the workarounds here for information:

First workaround

Change the repository configuration so that the branch with the slashes (/) in the name is default branch. Then start the workspace using the URL with no branch (For example https://<che-host>/#https://github.com/l0rd/inventory-quarkus).

Second workaround

Explicitly add the project in the devfile and use the raw devfile link to start the workspace.

This is the devfile in branch new/branch of the repo github.com/l0rd/quarkus:

...
projects:
  - name: inventory-quarkus
    git:
      remotes:
        origin: 'https://github.com/l0rd/inventory-quarkus'
      checkoutFrom:
        revision: new/branch
...

And it can be started using URL https://<che-host>/#https://raw.githubusercontent.com/l0rd/inventory-quarkus/new/branch/.devfile.yaml
