Money class accepts leading zeros for negative numbers

[Joris-van-der-Wel]

When I attempt to construct a Money instance by passing a value such as "01", anInvalidArgumentException will be thrown with the message "Leading zeros are not allowed". However, if I pass a value such as "-01" no exception is thrown and the Money class is created in an invalid state.

Example:

$ git clone https://github.com/moneyphp/money.git
$ cd money
$ git show HEAD

$ composer install
$ php -a

php > require 'vendor/autoload.php';

php > var_dump(Money\Money::EUR('01'));
PHP Warning:  Uncaught InvalidArgumentException: Leading zeros are not allowed in /projects/money/src/Number.php:248

php > var_dump(Money\Money::EUR('-01'));
object(Money\Money)#6 (2) {
  ["amount":"Money\Money":private]=>
  string(3) "-01"
  ["currency":"Money\Money":private]=>
  object(Money\Currency)#4 (1) {
    ["code":"Money\Currency":private]=>
    string(3) "EUR"
  }
}

Thanks for maintaining 😄
