Administration console - Store config change fails if wb is enabled, modal is opened and no value changed.

The issue is that when the user opens one of the pop-up dialogs in cache configuration (e.g. cache store -> Write behind), doesn't change anything and clicks OK, make some other changes, there is an error pop up when they try to save changes.

Steps to reproduce:
Set up a file store:
Cache container -> cache -> configuration -> Store tab -> Select file store -> apply -> ok -> restart later
Make a change:

• Cache container -> cache -> configuration -> Store tab
• change an attribute e.g. Read Only
• click on write behind (Don't change anything) -> click OK (WORKAROUND: if we click Cancel here instead of OK, everything works fine)
• apply changes -> confirm
  result:
  Error pop-up:
  {"WFLYCTL0062: Composite operation failed and was rolled back. Steps that failed:":
  Unknown macro: {"Operation step-5"}

  }
