SemVerException not Being Thrown

[jonmchan]

According to the phpdoc - https://github.com/vierbergenlars/php-semver/blob/2.x/src/vierbergenlars/SemVer/version.php#L26:

    /**
     * Initializes the version object with a simple version
     * @param  string          $version A simple, single version string
     * @param  bool            $loose
     * @throws SemVerException
     */
    public function __construct($version, $loose = false)
    {
        $this->version = new SemVer($version, $loose);
    }

but SemVer constructor actually throws \RuntimeException - https://github.com/vierbergenlars/php-semver/blob/master/src/vierbergenlars/SemVer/internal.php#L329. We need to either fix the documentation or what is being thrown.
