Invalid property type after an index deletion and recreation

[pkly]

When you change the declared property type in a document class like so

/**
 * @ES\Property(type="text")
 */
private $title;

To

/**
 * @ES\Property(type="keyword")
 */
private $title;

and then re-create the index by dropping it and creating it again, the field will not be updated in ElasticSearch.

It apprears that there's a cache issue, but even after doing the following:

ongr:es:index:create
ongr:es:cache:clear
ongr:es:index:drop --force
ongr:es:index:create

the changes do not persist.

The only way to update the document for ONGR is to add another field to the class.
