Delete multiple keys when using prefix

[NullP0int]

Multiple keys are not deleted when using prefix because the prefix is only added to the first key.

Expected Behavior

Delete all keys.

Current Behavior

Only the first key is deleted.

Possible Solution

Add prefix to every key.

Steps to Reproduce

1. Create a connection with prefix (e.g. cache)
2. The following snipped shows the deletion example

var keys []string{"a", "b"}
redis.Del(ctx, keys...)

This will produce the following Redis delete

del cache:a b

But it should be del cache:a cache:b to remove all keys instead of only the first one.
