Step deletion failures are politely reported

When trying to delete an in-use step, this is rejected with a polite
error message.

I did this by adding a `catch` clause to our fork of
`<EntryWrapper>`. Some day, I should probably make some kind of effort
to merge this back into stripes-smart-components.

Fixes last part of UIHAADM-9.
