Fix the url being set by WithURL on the getters
Fix the url being set by WithURL on the getters

The URL passed to the getter for WithURL needs to be a full URL
rather than a chart reference used at the CLI. For example,
bitnami/wordpress can point to the wordpress chart in the bitnami
repo where the bitnami repo is at https://charts.bitnami.com.
WithURL needs the full URL to the repo and not bitnami/wordpress.
This is important because getters use the full URL information.
In this case the http getter uses the host name for SNI handling.

Before this change WithURL was being set to the chart reference
instead of the URL. This was a silent bug.

This change sets WithURL using a URL after for the repo is
available when a reference is used instead of a full url.
