[FIX] tests: Handle attrs containing numbers instead of bool

The Form class already handles cases for attrs that contain boolean
values, e.g.:
`attrs="{'readonly': True}"`

But it doesnt for integers, e.g.:
`attrs="{'readonly': 1}"`

This commit changes the expected non-domain value from boolean to
integer, because both are valid cases and the former is a subset of the
latter.
