Release Mouse v2.4.4

https://metacpan.org/release/SYOHEX/Mouse-v2.4.4

Mouse with threads did not work on Perl 5.22.0 or higher version. This makes Text::Xslate test failure for a long time. This version fixed the issue and works with threads. Please upgrade for newer perl users.

Example

We expects $foo->syntax is "Kolon" but $foo->syntax is undef with older Mouse on Perl 5.22.0 or higher. This test is passed with Mouse v2.4.4.

#!perl
package Foo;
use Mouse;

has syntax => (
    is      => 'rw',
    isa     => 'Str',
    default => 'Kolon',
);

package main;
use strict;
use warnings;
use threads;

use Test::More;

my $foo = Foo->new;
is $foo->syntax, "Kolon";

threads->create(sub{
    is $foo->syntax, "Kolon";
})->join();
