Update CRW from multi host to single host broke "Create Workspace" page on Dashboard UI

Test case:
1. Install CRW 2.10.0 with default multi-host strategy.
2. Patch Che Cluster YAML:
change:
"serverExposureStrategy: multi-host"
to
"serverExposureStrategy: single-host"
3. Let operator finish update.
4. Open Dashboard and go to "Create Workspace" page

Actual result: broken icons of workspace tales, and an error message when try to create workspace:

Root cause: devfile registry returns devfiles/index.json with links for multi-host strategy, instead of single-host one:
index.json

Note: CRW 2.10.0.RC Single Host installation works as expected.
