MapCss Validation lost tag on misconstructed fixAdd

[frodrigo]

What steps will reproduce the problem?

1. Download object relation 8448338 (or any object with a tag wikipedia=NL:foo_bar
2. Active the Wikipedia ruleset validator
3. Validate
4. Select the validation Warning about: Wikipedia page title should have spaces instead of underscores (_→ )
5. Choose the fix button

What is the expected result?

The wikipedia tag should be now wikipedia=NL:foo bar

What happens instead?

The wikipedia tag disappear.
Because of two issues:

1. The validation rule is case insensitive

node[wikipedia =~ /(?i)^{[-a-z]{2,12}:.*_/][wikipedia !~ /(?i)}[-a-z]{2,12}:https?:/] {

But the replacement is not

fixAdd: concat("wikipedia=", get(regexp_match("^{([-a-z]+:)(.+)$", tag("wikipedia")),1), trim(replace(get(regexp_match("}([-a-z]+:)(.+)$", tag("wikipedia")),2), "_", " ")));

So the regexp_match match nothing, the two regexp_match should be fixed with "/(?i)..."

2. JOSM simple lost the wikipedia tag
