[FIX] base: fix t-field with empty value/default value

Since odoo/odoo#97347 we support default values for `t-field`
directives.
However this causes some issues in the case where we have: no value, no
default value AND force_display is true.
This is because the indentation for one of the lines in the compiled
code was not correct. (full explanation here: https://github.com/odoo/odoo/pull/97347#issuecomment-1222430659)

closes odoo/odoo#98714
