Calendar: fix creation of ICS Files

Summary:
It seems that, in an attempt to make ICS URI(s) editable, we broke the ability
to manually import ICS files. Whops.

The cause is, the URI needs to be put inside its dedicated import engine,
and not the general one.

Since the intention of T15137 was to be able to edit this field, we have done
that in the right way this time. So, you see the field, not just in creation mode.

Thanks to the kind aklapper for reporting.

Ref      T15137
Closes   T15619
Rollback 02a4f8b0c8

Test Plan:
- visit /calendar/import/ and:
- create/edit an ICS File Import (now works again)
- create/edit an ICS URI Import (still work)
- try looking at an "ICS Import page" as author (URI still visible)
- try looking at an "ICS Import page" without Edit permissions (URI still omitted correctly)
