fix: fix several field bugs (#5339)

After discussing with @charlesBochet, several fixes are needed on
fields:
- [x] Disable Boolean field `defaultValue` edition for now (On
`defaultValue` update, newly created records are not taking the updated
`defaultValue` into account. Setting the `defaultValue` on creation is
fine.)
- [x] Disable Phone field creation for now
- [x] For the Person object, display the "Phone" field as a field of
type Phone (right now its type is Text; later we'll migrate it to a
proper Phone field).
- [x] Fix RawJson field display (displaying `[object Object]` in Record
Table cells).
- [x] In Settings/Data Model, on Relation field creation/edition,
"Object destination" select is not working properly if an object was not
manually selected (displays Companies by default but creates a relation
to another random object than Companies).
