strictify() and _fill_default_for() in convert.py ignored
parameter.default_value for optional text params, hardcoding None
for absent values. Additionally both used `or` which swallowed
empty string defaults due to Python falsiness.
This caused inconsistent behavior for absent params on tools with
value="" across input formats:
| Input | optional (no default) | optional value="" | optional value="" + regex |
|-------|----------------------|-------------------|--------------------------|
| {} | None | "" | "" |
| None | None | None | None |
| "" | "" | "" | "" |
| valid | value | value | value |
| bad | value | value | fails |
All rows now consistent across legacy, 21.01, and request formats.
Test tools added:
- gx_text_optional_with_empty_default (optional text, value="", no validator)
- gx_text_optional_with_empty_default_regex_validation (the wild case)
- gx_text_optional_regex_validation updated to have no default
