[FIX] web : typo t-if vs if

To reproduce
=============
- on settings upload a custom background on document layout and save it
- open document layout again and try to download the image -> Traceback

Problem
=======
when calling download method we will ask server for a record with `id=false`
which gives an error

Solution
========
download button shouldn't be visible when `record.resId == false`
