formatMessage does not format when parameter is 0

[NielsFestjens]

In the formatMessage function:
var replacements = unwrap(params) || []; (should be around line 451)
when params is 0 (for example, when minimum value is 0), you end up with an empty array, so you get the message 'Please enter a value greater than or equal to {0}'.
I fixed this by replacing the code with

var replacements = unwrap(params);
if (replacements === undefined) {
    replacements = [];
}
