[FIX] web: create record with properties in Calendar

Before this commit, creating a record in Calendar view that has a
properties field in its form view causes a crash.

How to reproduce:
----------------
- Go to the Project app
- Go to a task
- Add a property
- Go to the Calendar view of the project
- Create a record

Before this commit:
    An error is displayed

After this commit:
    The form dialog opens so that you can create the record
