Providing spatialIndex parameters although it shouldn't receive any parameters

[MatanYadaev]

The package generates a migration file with spatial indexes and passes an index name as a parameter, although spatialIndex shouldn't receive any parameters.

<?php

// Current:
$table->point('location')->spatialIndex('apartments_location_spatial');

// Should be:
$table->point('location');
$table->spatialIndex('location', 'apartments_location_spatial');
