This patch replaces force=true with %s in rest-api translation strings.

The translators should not have access to code like force=true, they can accidentally change some characters.

When using code in translation strings we should always use %s placeholders.

This is good, but I think the translator comment can be improved to better explain what force=true is.

[ramiy]

@johnbillion This is the common practice. We usually use the file name, function name or code example in the translator comments. But if you have a better explanation, I'll update the patch.

[johnbillion]

In that case, fine by me.
